Hi, Just discovered this cool video by Jeri Ellsworth that is on YouTube. The first part many of you probably know already (but I found very educational), but I'm sure you'll all enjoy the last part (exploding capicators, captured at 1200fps). http://www.youtube.com/watch?v=Uq5gLrGumR0 Regards, Andrew B aliensrcooluk at yahoo.co.uk
