Aluminum Foil Electroscope

An Electroscope is an apparatus that is used to detect electrostatic field, it shows in a visible way the presence of an electric charge, with one you can even have a quantitative idea about how strong is the field. The simple electroscope proposed here is constructed with minimum and common materials and in fact you can build one right now in your kitchen.

Step 1: Materials

You will need only a glass jar with plastic cap and Aluminum foil roll.

that was good but i also made an electroscope like this but i need to know weather we can use a battery to make that work

thaannkkk good a sweear maa phyisics techear hee waas goona kill mee finaly:P

[spylock]

How do you know its working,what does it do?

[nittosuleh]

the unicorn will fly out when charge is passed through the aluminium ball


ITT: the two flaps will move apart

[ilpug]

oh so thats how you make it! we spent forever in our physics class trying to make one of these and it just wouldnt work.

Had to modify a bit. Instead of bending the rod and folding one piece of foil over it, I used a paperclip at the end to hang 2 aluminum foil strips more freely. That way they could detect a smaller charge. Thanks This has worked great in class.

good >> very nice
