Making a Mercury Switch
Remember that experiment about mercury? I tried to show you that mercury can conduct electricity. And it did. I studied it a little bit more and I found this:
A Simple (Tilt) Mercury Switch:
It’s similar to the one we did the last time. Instead of tilting it around, what if you suck the mercury in and out. Isn’t that better? I’ll try to build one just for fun.
I made a hole in a little container (what don’t know what to call it) and put a syringe in there. Then, I poked holes in the bottom and glued 2 wires in, and poured the mercury in.
Works pretty nicely. I hoped you enjoyed!
