Day One

A treat of a challenge - a rocket to lift up an egg, and some mechanism to keep the egg intact.

I'm using water under pressure as a propellant, Mikey B is using gas and Jonathan using steam.

Jonathan isn't sounding enthusiastic about steam, but he's giving it a go. Mikey B is working like a trooper again, missing lunch to keep working. And I'm getting to play around with a bike pump, a ridiculous spanner-release system and empty plastic drinks bottles.

It's stonkingly good fun. The crew and production team can barely keep their hands off, they so badly want to make rockets too. Kate's enjoying it enormously as well - and we all just keep getting covered with water: me , Ellen, Kate, Ian, the crews, and the cameras.

What a treat!
