I have also seen science experiments where water was boiled in a waterbomb (bunsen burner, gauze mat) - the water stops the paper from burning - quite surprising
I, on the other hand taught my kids to make them as a fun activity on a hot afternoon, with a cool watery payoff - they throw full of water quite nicely but do not survive catapult flings very well, sadly regards Peter Whitehouse* http://www.wonko.info *some assembly required ------------------------- Email sent using Optus Webmail
