If you conduct experiments on electrostatics or help your children in this, then you can hardly do without the simplest device for determining an electric charge - an electroscope.
It is necessary
- foil
- transparent glass vessel (for example, a jar) with a plastic lid
- a nail or piece of wire
Instructions
Step 1
Make a small hole in the lid of the can, just enough for a nail (or wire) to go through.
Step 2
Slide a wire or nail into the hole, bend the bottom with a crochet hook.
Step 3
Attach a strip of foil to the folded end of the wire (tissue paper will also work).
Step 4
To increase the capacity of the device, the upper part of the wire (nail) can be rolled up in a spiral, or a plastic ball wrapped in foil can be put on it.
Step 5
Close the jar with the lid and your new electroscope is ready to use.
