EISCOLabs Aluminum Leaf Flask Electroscope

I had to demonstrate the effects of static electricity for the nuclear science merit badge. This kit worked just as described.

The unit works very well however the foils easily jump off the holder. Handling will cause the foils to drop off and het the bottom. Ok for closed enviornment, not great for hands on type of environment.

This is a basic electroscope, but it's effective at detecting static charges. My only quibble is that the aluminum leaves aren't factory attached, and it takes a steady hand and a pair of tweezers to slip them onto the brackets - the slots are very small and thin. Once assembled, though, it's a great item.

The seller spends quite a bit of energy in the description with regard to touting their interest in assisting education but the scope comes without instruction. For those of us who are physics curious but without a lab background, it took some digging to figure out how to get the foil to attach without damaging the leaves. Eisco can get their additional 2 stars if they include some guidance.

I love alternate energy and experimenting so this was a great item to add to my collection. I immediately put it together once it arrived. I had no trouble getting the aluminum foil onto the holders. It can tear easily so be careful and patient here.But it is so sensitive that the foil was attracted to the bottle itself when I was inserting it. My daughter loves to play with this.It is humid right now but in winter this is going to be great fun for the family.

The media could not be loaded. The leaves come in a separate plastic bag. You will need to be gentle as they are delicate! I used hemostats and a gentle touch.With a bit of styrofoam and a dogs fur I got full separation of the leaves. Note that unlike some electroscopes, these leaves are separated by about 1/2" by the metal holder. . It was quite humid when I tested this, and I had not put desiccant in the bottle beforehand. The leaves separated easily, but fell right back when the charge was removed. I expect dry air would have worked much better.For the price, the build is quite good. This works for me.
