Food-grade aluminum foil is sold in almost every grocery store. Of course, we all know its main use. But there are other ways to engage and use this interesting material. Here are three ideas below.
Will need
To do all three crafts need to:
- Food foil.
- Self-tapping screws pair.
- Soldering iron.
- LED Strip Light.
- Pen with transparent body.
- A couple of nails.
- Krona battery and a large 1.5 V battery.
Antistatic keychain
Oh, this is a very useful thing for those who are constantly hit by static discharges. This happens mainly in winter, when the air is dry and static can easily accumulate on you. If you need to touch something metallic, an unpleasant discharge occurs. This can be avoided by using a special discharger - an antistatic key fob. It's done in a couple of minutes.
We take out the paste with the cap from the pen.
We saw off a piece of about 3-4 centimeters from the body.
We insert a self-tapping screw on one side with the head inward and glue it evenly with hot glue.
We roll a not very dense but strong ball out of foil and insert it into the inside of the tube.
We glue the same self-tapping screw on the other side.
The keychain is ready!
Now, to check, rub a rubber ball on the wool. With our hand we hold the keychain by one screw, and with the other we touch the object from which we need to remove the charge.
At this time, a ball of foil begins to run inside the keychain from cap to cap. As soon as its movement is over, the charge is released.
Position sensor
We saw off another 3-4 centimeter piece from the same handle.
Fill one side tightly with glue.
Insert a ball of foil. Next, insert two small nails halfway and fill them with glue.
While the glue has not cooled and hardened, distribute the nails evenly so that they do not touch.
Now the ball inside can close the nails. A kind of switch.
If you connect such a sensor to the open circuit between the LED strip and the battery, when the sensor is tilted, the ball will close the circuit and the LED strip will glow.
Hand warmer in 5 seconds
If your hands are cold, take a piece of foil and wrap it around a large 1.5 V battery (you can use a small one, but it won’t last long).
Since you actually shorted the poles of the element, the foil began to act as a load and began to generate heat. Now you can warm your hands with this bundle one at a time.
Once you have warmed up, remove the foil from the batteries, it should be enough for a couple more times.
