    What do you think are some of the coolest, most fun, or most interesting chemistry experiments to do at home, and how did you do them?

    It's got to be the gold penny trick. You need a penny some zinc solution and a propane torch.

    Copper(II) Chloride will react with Aluminum powder and give off multi-colored (purple, yellow, white) fumes. This is a very cool reaction to watch.

    Any of the Belousov-Zhabotinsky reactions (if you can pull one off) are quite neat to watch.

    Googling 'Belousov-Zhabotinsky reaction"......

    Oh yeah! Oscillators, very cool...

    Exposing muriatic acid fume to household ammonia fume.
    Produces a dense white smoke. Probably not good to breathe though.

    Also when I was a kid we used to put vinegar and baking soda in an old wine bottle and see how we could shoot the cork, outdoors of course.
