Need - One small Microwave. soon to be useless. Need parents permission too. don’t try this at home. unless you’re a professional arsonist.
In another thread it’s noted that microwaves will dance prettyly over a cd. They do - Place doomed disc in microwave and set to 5 seconds - make sure it’s a dark room. Enjoy cascading lights.
For a more spectacular show - get some fresh green grapes from the store. Slice in half and lay them wet side up in a plate. as close as you can get them without actually touching each other. Fire up Microwave, and wait a sec or two - Bolts of Plasma should start leaping from grape side to grape side - Listen to that Microwave change power levels! WOOT! (yes, I’m serious - we’re talking lightning bolts)
