I'm sure everyone must remember a school open night, and Keith will certainly know them better than most!

Not everyone sees them from a staff side, but they make for a lot of bloody hard work and a very long day!

I took lots of photos of cool stuff, some of which are safe to post here, but they're all in work as I didn't send myself any!

I've now remedied that, and the one we've gone for is a lovely plume of flame from some methane bubbles. Trickle a gas tap through soapy water and you get a soap sud lather filled with methane instead of air. Grab a few handfuls and spread them out across a surface and then light and run. :)

And remember kids, this was on heat resistant mats behind a safety screen - don't try this on Mum's worktop ;)
