    im trying to stimulate my sons already active imagination.
    we bought him a very simple chemistry set last xmas and hes enjoyed it so far but..they are slightly boring experiments and id like to have any ideas that might freak him out a wee bit more hes been waiting for an explosion for ages and ive managed to improvise some good ones so far using whats in the set, popping the rubber bung out and stuff but can anybody suggest some ideas using readily available chemicals?
    thanx
    (i know nothing about chemistry so bare that in mind too)

    -Cornflour and water; flows like a liquid but is solid to the touch.

    -Vinegar and bicarbonate of soda

    vinegar and bicarb froths up spectacularly, but safely. It is often used to make models of volcanoes.

    How about giving him some caustic soda and oil for him to make soap. That would be interesting. After that, you can still use back the soap for household use.

    Concentrated sulfuric acid and sugar. Put some sugar in a cup up to half way and poor the acid on it. Must be done outside and away from anything valuable though. Don't smoke while doing it and obviously keep the ingredients away from your son. It was safe enough for my chem. teacher to demonstrate it in the 9th grade though.

    What happens is a black porous carbon cylinder comes out the top. Be careful of the hydrogen fumes though. Looks cool!

    A little dangerous for the amateur and conc H2S04 is harder to get .
    By the way the fumes are steam not hydrogen, the sucrose hydroxyls are converted to water leaving the carbon chain.

    Magic Through Science by Robert Gardner is a book with a lot of simple home expreriments in it. Amazon has it plus several others.
    Have fun, be careful
    Found a source of reasonably priced chemicals and equipment
    they also have a list of experiments
