Simple and easy to do scientific inventions, what are the simple inventions

The small invention in daily life, the set of washing socks, after each washing clothes, the pairs of socks are picked out to hang is often a troublesome thing, although the pairs of socks can be fixed with decorative buckles before washing to solve this problem, but this method is easy to deform the washed socks, and it is not comfortable to wear, and it is not suitable for women's nylon stockings.

Hang the hanger where you have your clothes hung on a rope (bamboo pole).

The clothes hook can effectively keep the clothes in the specific position of the clothesline, and the clothes do not rotate with the wind, affecting the adjacent clothes, so that the clothes are air-dried and evenly sun-dried clothes will no longer move with the wind, fight with each other, and the clothes will not be pasted before and after, easy to dry, and will not transfer color.

A simple gizmo has a mobile phone holder, and the method is as follows:Tools required: paper cups, scissors, utility knives, markers.

The first step is to draw the pattern to be cut on the paper cup with a marker, as shown in the figure below

Step 2: Then use a utility knife to remove the bottom of the paper cup, as shown in the figure below

The third step is to crop along the drawn diagram, as shown in the figure below

The fourth step and the last convenient and practical mobile phone holder are completed, as shown in the figure below

The practice of scientific gizmos is as follows:1. The battery must be selected to be attracted by the magnet.

2. The magnet should be the same diameter as the battery and have a conductive metal plating.

3. Absorb on the negative electrode of the battery and ensure that it will not be short-circuited.

<>5. It should be noted that the two edges below the copper line should not touch the magnet at the same time, and there should be a gap.

6. Adjust the upper and lower heights so that the current can pass through the copper wire on one side at a certain time to generate a loop.

7. Place the copper wire on the battery.

8. The small motor has begun to spin, so if you are interested, try it yourself.

Science is an orderly knowledge system based on testable explanations and the form and organization of objective things, and it is knowledge that is systematized and formulaic. According to the fields to be reflected in the knowledge of these (scientific) systems, they can be mainly divided into natural sciences, social sciences, thinking sciences, formal sciences and interdisciplinary sciences.

Science is a system of knowledge that is based on testable explanations and the form, organization, etc. of objective things, and is knowledge that has been systematized and formulated. Its object is objective phenomena, its content is formal scientific theory, and its form is language, including natural language and mathematical language.

How to do scientific gizmos:

The first tools we need to prepare are batteries, magnets, and copper coils. Attach a small magnet (both n or s) at the same pole to the positive and negative poles of the battery. Then put this made battery into the copper coil.

At this time, you will find that the battery is constantly shuttling in the copper coil.

Small magnets are the key point of this experiment, they not only produce a magnetic field, but also act as a conductor, so that the copper coil and the positive and negative poles of the battery are connected, even if the current is generated in the copper coil, the energized copper coil generates a magnetic field according to the law of electromagnetic induction and the right-hand rule.

How to prevent the production of water full technology inventions:

1. First of all, use an iron bar to wrap it into a U-shape and intersperse a foam block;

2. Then glue a small wooden board at the ends of both sides of the iron bar, and then glue two copper wires wound into an S-shape;

3. Then connect the battery and a buzzer together, and then solder to two copper wires, only two copper wires need to be connected to make the buzzer sound;

4. Then stick an additional piece of foam block with an iron ring on the foam block;

5. Finally, glue a wooden clip to this device, when the water is full, the foam block will touch the copper wire with the rise of the liquid level, and use the iron ring to connect the power supply of the buzzer to achieve the effect of prompting. Reverse one reversal. The form, nature, and function of a certain thing are reversed to create a new object.

Many new products tend to be reversed from top to bottom, inside and outside, left and right, front and back, horizontal and vertical.

A shocking few scientific gadgets, and they're easy to pick up and easy to make!

Simple-Material: One water bottle. A thicker needle. Water.

Procedure: Put 2-3 cm at the bottom of the water bottle and poke n holes with a needle. After filling with water. The cap will not leak when screwed on. If you open it, it will.
