Given the mica is repelled by oil, I'm wondering if it might be possible to make rheoscopic wave or other toys. They're usually made with coloured water and an oil on top, often baby oil, but adding mica to the water might be pretty cool.Obviously you wouldn't want the mica to migrate into the oil, but if it's repelled by the oil it probably wouldn't anyway. (It probably will a bit, but it will tend to settle back out into the water.)

I used a rechargeable NiMh battery. I measured it at 8.4v.Maybe snails are less sensitive.

I stripped off the insulation, it was mains electrical wire. Didn't notice any slugs but there were snails that had got past.

I tried this with copper wire and a 9v battery, but it doesn't seem to be working for some reason; the snails just go straight past it. Does it have to be galvanised?
