Flask form electroscope with aluminum leaves. Just touch the top of the knob with a charged object, and the leaves will separate. Bigger charges cause more separation. Includes 250 ml flask, stopper, plated rod with knob, and aluminum. Pair it with our Friction Rod Kit to have a complete lesson on static charge and polarity!
Note: Due to problems with gold leaf we have replaced with aluminum.
