A year or so ago someone posted a link to a gentleman's website where he had several toys.
Things like using a piezo electric lighter, to ignite hairspray, to propel a bean can up into the air. Also, he had a small 'jet boat', that could be used in a bath tub and was powered by a coil of small dia. copper tubing, that was heated by some type of flame.
Sorry if this is a little vague but, if I could be much more specific, my own searches would probably have found it. :-)
Your help will be appreciated.
Lewis.
