Thank you!

Just let them take apart stuff with batteries instead of anything that
plugs into the wall.

If they are really into it, get them some kits to build. When I was
probably 8-10, I had the radio shack kits that comes with jumper wires
and springs. You can build a fair amount of cool stuff with it
safely.
