Eisco Labs Pith Electroscope

These stands are lightweight, but not prone to tipping, and have no obvious weaknesses.Am considering hot-gluing a large, heavy washer into the bottom of each, for extra weight, but they are really quite good.At $5 when bought as an add-on item, these really cannot be beat for the price!I run a group of seven teachers who teach after-school science classes at schools all around our area -- we demand durability and this meets our needs.

I couldn't seem to get this to work. It may be very sensitive to atmospheric humidity oh, but it doesn't seem well-constructed. I'm pretty handy with little science toys usually so I'm probably not doing it wrong

Worked fine as demo for high school students,,thanks
