Winter vacation, I want to make a small invention, I don t know what to do, help 10

Postcards and envelopes.

Stamp toys are not only enjoyed by children, but also by many adults. By applying paint to the leaves and stamping them on paper, you can make a seal with a sense of the season. Many things in daily life can be used effectively to make seals.

For example: cuts in vegetables, empty shells, erasers, etc.

Spare items: leaves (there are nearby), pigments (ink can also be used), tissue paper, postcards, envelopes

1. Melt the pigment with a small amount of water and apply it to the leaves with a brush.

2. Put the painted leaves on the postcard or envelope, cover it with thin red, and wipe it.

3. Repeat this process according to the pattern you designed, and dry it overnight. Once it is dry, you can write on it. The same procedure is for making envelopes.

My briquette stove has to be pulled out with a fire puller, and every time it is used up, the fire pipe is very hot. I think this should be utilized.

Some heat, do things for people. So, I soldered a kettle outside the torch. So the fire was raised.

When it came, the water in the pot was also hot, and it saved coal and hot water.

Use an ordinary aluminum pot to cook rice, when the stove is very hot, the flame will burn the pot ears very hot, or even put it.

The ears of the pot are burned. In order to prevent the flame from burning the ears of the pot, I wrapped a circle of wire under the ears of the pot and cut a piece of iron.

Two notches, inserted into the aluminum sheet under the ears of the pot. The middle end of the iron sheet is stuck at the bottom of the edge of the pot, and there is iron in the middle of the iron sheet.

If the silk is supported, it will not fall off.

This piece of iron can block the flames, so that the flames cannot burn the ears of the pot, and the pot will no longer be hot.

I was willing to help my mom with the housework, but I was afraid to boil the water. Because the lid of my aluminum pot is very loose, when the boiling water is about to be poured out, the lid often falls off by itself. The boiling hot steam rushed right to the hand, and it was hot.

It hurts me. Later, the school called on us to make small inventions. I thought: can you think of a way to make the lid of the pot open?

The water doesn't fall off After much deliberation and experimentation, I finally came up with this simple and effective solution.

Law. Roll a cylinder at one end of a 3-4 inch long aluminum or iron sheet, thread an iron wire, and bend one first.

wire box, and then tie the box tightly to the pot beam. When filling, the pot beam is tilted, and the aluminum strip automatically sags, just pressing the lid of the pot, and the lid can't be turned over.

Convenient lid opener, fix a fast magnet on the ordinary lid opener, and open the lid to suck on the convenient lid opener.

When the ignition device of the gas stove is broken, use a lighter to ignite it, this is a small invention.

Thank you, help me solve an assignment problem.

I played it when I was in elementary school.

Materials: One battery (preferably a large battery, not the usual No. 5 battery) and a flashlight bulb.

A hole in the middle, like a copper plate or a dime coin (preferably round), and a thin wire.

Method: Use a wire to talk about "bulbs" and "things that punch holes" to connect, and it's OK Simple) Usage:

Talking about one end of the light bulb, aiming at the positive level of the lead-punching battery, talking about the "punched thing" pressed with the battery, the light will be lit up.

It's a simple electric spine bulb

It's a little invention

I remember doing it in elementary school and getting a little red tweed.

Haha, recommended

Think about cleaning, clear the dirt in the corners, use chopsticks and small brushes, so it's more... It is recommended to take a look at trick shows such as "The Queen of Housekeeping", which can also be used for reference.

No batteries are required, no flashlights are required to recharge. It's not difficult, right?

Natural humidifiers (i.e. those that do not require electricity.) I've made a simple and decorating one from my own waste, and I'm sure you'll do better).
