How to make an hourglass, how to make a manual hourglass is the easiest way

Factors that affect the hourglass of time include: the amount of filling, the curvilinear shape of the inner wall of the glass ball (there are slight differences in the length of the hourglass upright and inverted), the width of the neck pipe, the type and quality of the filler. The earliest hourglasses used tomb marble grinding powder, iron filings, and eggshell powder.

Modern hourglasses, on the other hand, generally use artificially made glass beads. Some hourglass manufacturers make hourglasses, the error of 30 minutes can be controlled within 1 minute, and the error of 1 hour hourglass is about 5 minutes. Note:

It is not a chronograph instrument that can be compared with the accuracy of modern chronometric instruments.

Second, the production method of the hourglass, step by step introduction:

1. Find two beverage bottles of the same height, remove the two caps, drill 3 symmetrical holes in the same direction on the two caps, fix the two caps back to back together with screws, and then drill a larger hole in the middle of the two caps as a sand leakage hole.

2. Go to the construction site to load two bottles of clean fine sand and come back, dry it for later use.

3. Find a screen mesh, make a small sieve, sift out the coarse sand, leaving fine sand, if the sand is not fine enough, put two or three layers of sand mesh on the sieve, and then sift a weave to leave finer sand.

4. Fill one of the bottles with the fine sand sieved out, then close the connected caps tightly, and then fill the empty bottles as well. A simple hourglass timer is ready (fixing the two caps with screws is better than using glue and is very firm).

5. Turn the bottle upside down, so that the bottle full of sand is on it, you can see the fine sand leaking from the hole in the middle of the bottle cap to the bottle below, if the sand leaks a little stuck, then increase the hole of the sand leakage a little more until the sand leakage is very smooth.

3. Precautions and necessary supplements:

Once the hourglass timer is ready, it's time to use it to measure the time. When the hourglass timer is turned upside down, it takes a few minutes to see that all the sand leaks into the bottle below, and mark the position of the sand leaking every minute with an oil-based pen during the timer. When you see the sand at this point when you use it, you know how long it has been.

Sand (I used one of my hourglasses to break it, the blue sand in it is made, if you don't have it, you can go to the small shop and ask if you can buy it, it's very cheap.)

2。Bright powders of various colors, also known as phosphors. (Sold in a small shop).

3。Your favorite bells, pendants or decorated keys and bracelet balls.

4。Two small glass bottles, the same size, (I gave them when I bought phosphor.) Production:

1。Remove one of the covers (it is useless) and make a hole in the middle of the other, (be slightly larger, otherwise the sand will not circulate).

2。Put the sand in one of them and the powder as well as stirred, and then divide the decorations into two bottles.

3。Glue the two bottles together with duct tape, and be sure to cover the end where the sand is placed so that it doesn't leak out.

4。Just cut off the excess part of the tape.

Actually, the production is very simple, I finished it in one morning, it's quite cute, I hope you like it.

The principle of making an hourglass, how to measure the amount of sand in ancient times.

The hourglass, also known as the "sand clock", is an instrument for measuring time in ancient China. The hourglass is made on much the same principle as the leak carving, which measures time based on the amount of quicksand leaking from one container to another. This method of using quicksand instead of water is because the air in northern China is cold in winter, and the water is easy to freeze.

The most famous hourglass is the "five-wheeled hourglass" created by Zhan Xiyuan in 1360. The quicksand flows from the funnel-shaped sand pit to the sand bucket on the side of the primary wheel, which drives the primary wheel, thereby driving the mechanical gears of all levels to rotate. The last stage gear drives the middle wheel, which rotates in a horizontal plane, with a pointer on its axis, which in turn turns on a notched instrument disc to display the time, almost exactly the same way as the surface structure of modern clocks.

In addition, Zhan Xiyuan also cleverly added a mechanical toggle device to the middle wheel to remind the two wooden figures standing on the five-wheel hourglass to beat the drum to tell the time. Every hour or hour, two wooden figures will come out on their own and beat the drum to report the time. This hourglass has become a mechanical clock structure in its own right, separated from auxiliary astronomical instruments.

Make your own hourglass from scrap materials.

Find two empty water bottles, then cut off the top half with scissors, plug the cut with white paper, and then glue it with transparent glue, which is the same for the other water bottle. Pierce the lids of both water bottles with an awl, unscrew the cap of one bottle, and fill it with sand of about the same size and both of them can pass through the holes. The final step is to attach the caps with clear glue, so that an hourglass is made.

Don't forget to decorate your creations.

Make your own hourglass from scrap materials2

Ingredients: Two cups of jelly after eating;

two small discs;

two plastic sheets that cover the center hole of the disc;

some sifted fine sand;

502 glue [use under adult supervision, pay attention to safety].

Production process: 1. Wash the two jelly cups first, and drill holes in the center of the bottom of the cups with the help of adults;

2. The bottom of the jelly cup should be glued with 502 glue;

3. Glue the plastic sheet with 502 glue to the center hole of the disc;

4. Glue the two discs to the rim of the jelly cup (don't forget to put sand in the hourglass 5. The hourglass is finished.)

To make a DIY hourglass, you need to prepare two small plastic bottles, a pile of sand, a super glue, and a roll of transparent glue.

First add half of the sand to a plastic bottle, then dock the mouth of the other plastic bottle with the mouth of the plastic bottle filled with sand, then apply glue, then roll transparent glue on both mouths, and then apply glue to the transparent glue, so that it can ensure enough stability to prevent the sand from leaking out, and then you can add some decoration to the outside of the plastic bottle. The hourglass can also be filled with sand of various colors, so that the colors can be richer.

You can also make a funnel of water, add water to the water and drip in a variety of different colors of ink, so that you can produce fantastical art.

How to make a handmade hourglass is simple, on the first floor, I think that the handmade hourglass can be made according to the materials you have at hand. The funnel is particularly simple and applied.

Hello. Of course, it is good to use a mineral water bottle or a glass of sand, and of course the necking should be relatively small.

If you want to make a handmade hourglass, the easiest way is to use a leak net yourself, and then, put a leak net in the bottle, fill it with some sand yourself, and then let him put it on it.

The hourglass wants to make it leak quickly in two ways: tilting it and shaking it.

The hourglass can be placed obliquely to make the hourglass leak faster, the hourglass is calculated by the normal fall of the sand particles in it, and the stable hourglass movement speed is uniform, so the hourglass is placed obliquely, so as to increase the flow speed of the sand particles, and the sand particles in the sedan car are promoted to the faster leakage of the sand particles in the hourglass.

Shake the hourglass. The fast hourglass leak needs to be shaken by hand, hold the hourglass in your hand steadily, and then shake it from side to side, do not shake it up and down, the sand particles in the hourglass move more violently in the process of shaking, so as to promote the flow speed at the leak, and the hourglass will leak faster.

Hourglass introduction

It consists of two white pedestals and three transparent pillars, and in the middle is a "gourd" composed of two transparent glass covers in the shape of water droplets. It has many purple grains of sand in its glass enclosure, which can flow from one pane to another through small holes. That's right, it's an hourglass.

The hourglass, also known as the "sand clock", is a timekeeping device in ancient times. The working principle of the hourglass is basically the same as that of another sail-carrying tool in ancient China. The loss of the front is timed based on the amount of water flowing from one pot to another, while the hourglass is timed by the amount of sand leaking from one container to another.

Refer to the above content: Encyclopedia - Hourglass.

You can make a simple hourglass with an empty mineral water bottle and a straw.

Materials and tools to be used: melt glue gun, 2 straws, 2 empty water bottles, scissors, and coloring (or colored paint).

Production steps: 1. Use a hot melt glue gun to glue the lids of the 2 water bottles back to back.

2. Then use scissors to drill 2 holes in the lid, and his size is just enough to pass through the straw.

3. After threading the 2 straws out of the hole, a small section is exposed (in this process, you can use a hot melt glue gun to stick the connection between the straw and the lid, or you can wrap a circle of hot melt glue around the periphery of the 2 lids to seal and reinforce).

4. Finally, we pour some water into the bottle, add a few drops of pigment, and then screw the bottle and the cap together.

Scientific: When the two straws are threaded out of the cap, they are combined to form a device for the flow of water and air pressure. Because of gravity, the water in the upper bottle will flow downward, and due to the air pressure, the water in the lower bottle will run upward, thus creating a water hourglass effect.

First of all, prepare 2 plastic bottles of the same size, scissors, glue and transparent glue, sand, and a kind of cardboard similar to courier paper, prepare a compass, art knife, and black line pen.

Then first put the plastic bottle mouth on the cardboard and draw a circle with a black line pen, then cut out the circle, draw a circle from the inside with a compass, and then use an art knife to cut out a concentric circle from the inside, dip the concentric circle on the concentric circle, put the concentric circle on the mouth of the plastic bottle, stick it well, pour the sand into the plastic bottle, stick another plastic bottle on the other side of the concentric circle, and finally wrap the plastic bottle mouth with transparent glue to stabilize the bottle mouth, and then it is completed.

The hourglass expresses a sense of farewell, and the process of spilling sand is also a process of reminiscing about the beautiful moments between friends. The sand of the hourglass is a beautiful memory between friends.

The first approach:

Tools Raw materials.

Coke bottles, sand.

Method steps.

1. Two empty Coke bottles, the bottle mouth is placed on the cardboard and the outline is outlined with a pen.

2. Draw a small concentric circle in a large circle.

3. Use a knife to cut out the small circle, and cut off the cardboard on the outside of the big circle with scissors.

4. Pour the sand into the Coke bottle.

5. The concentric circle cardboard is glued to the mouth of the cola bottle.

6. Glue another cola bottle and wrap a circle of tape on the outside.

The second approach:

Materials: 2 bottles, rice or sand, scotch tape, glue sticks.

Steps: 1. Put the rice or sand into a bottle first, in the middle of the bottle;

2. Use glue sticks to coat the spouts of the two bottles with glue;

3. Butt the spouts of the two bottles together;

4. Fix the spouts of the two bottles with scotch tape, and a small handmade hourglass is completed.

If you make a glass hourglass, first use 2 high-temperature resistant goblets to burn through the bottom with oxygen welding, weld the two cups, polish them smoothly, put a certain amount of sand inside, fix the two cups with wooden boards (you can choose other boards), and then use a few small pillars to evenly fix the two wooden boards, try and then adjust it.

The hourglass is made as follows:

1. First of all, we should start from making sand, using a desiccant called silicic acid, put it in a pot and heat it with fire to evaporate the excess water, so that the sand has only 20% water content, if it is too dry, the sand is easy to stick to the glass wall.

2. Cut the glass tube into the size of an hourglass, and each glass tube after cutting is the prototype of the hourglass.

3. Use high temperature to process the shape of the hourglass, the temperature is very important, first use the low temperature to heat the glass tube, pull the softened glass tube from both sides, and make a narrow pipe in the middle of the hourglass, and the size of the pipe depends on the experience of the worker.

4. In order to make the glass stand up by itself, make the bottom from the end of the glass tube, heat the end of the glass tube and press it with small pliers while turning and pressing, until the edge of the bottle is made, and finally seal the end of the glass.

5. The upper and lower parts of the hourglass are round glass balls, which are made by manually blowing and processing the glass by heating it at high temperature and softening it.

6. The next step is to fill the glass tube to be sealed, adjust the amount of sand with time, and repeat many times to correctly measure the amount of sand. Add a bottom to the other end of the glass tube where the sand is placed, and make the rim of the bottle with the same high heat and pliers and seal it. Just like that, a complete hourglass is complete.

How to make it:

1. This is an hourglass made according to their own design drawings, an hourglass of observation, think about it, what are the steps needed to make such an hourglass?

2. We make it by making the bottle body, refilling the sand, remaking the interface, and finally beautifying. (Board book: bottle body - sand filling - interface - beautification).

3. Bottle production.

1) The skills of cutting and splicing bottles have been learned in the last lesson, and I believe everyone still remembers.

2) To make such an hourglass, how many bottles do we need to cut?

3) What should I pay attention to when cutting these two bottles?

If two bottles are exactly the same height and size, they will be placed more ( ) Of course, sometimes asymmetry can also give us another feeling.

4. Sieve sand and fill sand.

1) Make the bottle, and then (fill the sand), whether the sand flows smoothly and evenly is the key to accurate timing, so do you think it is appropriate to pour such sand? (Projection a cup of impurity sand).

2) So I have to use a sieve to sift out impurities and large particles before filling the bottle.

3) In this way, the texture of the sand sieved out is very uniform. (Demonstration of sifting sand).

4) The cup of sand we just saw is fine sand that has been washed and selected, and this kind of sand is generally used for hourglasses.

5) After sifting the sand and then filling it into the bottle, who will help the teacher hold the bottle? Then fill the sand in, the amount of sand is poured according to the length of the timing, under normal circumstances, half a bottle is filled first, which is convenient for adjustment.

5. Make an interface.

1) After filling the sand, it is necessary to make a pipe to connect the bottle mouth.

Let's first look at the pipe mouth of this hourglass, what are the characteristics of sand when it flows?

Board book: slowly, evenly, smoothly.

2) How do you make a pipeline to meet these requirements?

The mouth of the pipe should not be too thick or too fine, too coarse and the sand ......, too fine ......

3) What material is suitable for the pipe mouth?

4) Is there any other way to make a channel other than using a bottle cap? (Poke a small hole in the piece of paper.) ）

This method can also be used, plastic sheets, aluminum sheets, etc. in life can be used to make channels.

5) Compare the advantages and disadvantages of materials: Which of these materials is the best to choose? Why? (Demonstration: If the cap is adjusted, it can be connected back immediately, if it is ...... with a piece of paper.)It's more troublesome. ）

6) After screwing the cap, see if the sand flows smoothly, what if you feel that the sand flows too slowly? What if it's too fast?

7) When bonding, the two people cooperate, don't drip too much glue, wait for 10 seconds, and use a stopwatch to time it after connecting.

6. Beautification methods.

1) To make your hourglass more beautiful, landscaping can be the finishing touch. (Look).

2) What other ways do you make your hourglass more aesthetically pleasing?

7. Summary: Students, the production of the bottle body determines whether the hourglass is placed smoothly, the choice of sand determines whether the timing is accurate, and beautification can make our hourglass more beautiful. Every step in the production plays a vital role in the quality of the hourglass.
