Cork the top with a tube running out of it and into a bucket with soapy water. The reaction produces hydrogen gas which is what the soap bubbles will be filled with. Light a candle. Run your hand under some water, scoop up the bubbles, and stick your hand over the flame. FOOM! your hand "burns". But thanks to the specific heat of water, at the most your hand will feel a bit of warmth
That looks scary. But awesome! I've got to try this!*

Fun with Microwaves
My (physics) teacher told me about putting a cup of distilled water in a microwave for a couple minutes. Nothing happens to it, but one you put some form of impurity in it (dust, coffee powder suggested), it blows up. I've never tried, because my microwave isn't expendable, but can anyone confirm this?
Also, is tesla coil considered a home experiment? (Project, more like.) I've been wanting to build one for a while, but my grades would probably suffer.
Other than that, I don't know... but I like to play with fire! Get matches and contruct things out of them, and light it. Also tried some other things, like paper, thread, wood. There was also this one kind of tissue that gave out a more bluish fire (never buying that brand again.)
