Today was the day we exhibited Theremins and video feedback at Science World as a part of their 'Around the dome in 80 days' festival. I was a little unprepared for the seven hours of Theremin pitched sound accompanied by the general shrill of hundreds of small children enjoying interactive exhibits. It was fun, people loved it and we talked a lot!

I did manage to escape for 20 minutes and found a cycling exhibit where you peddle as hard as you can which causes a ball to float in a tube. Today I'm pleased to announce that I beat all the 5 year olds to the best time of 1 minute and 46 seconds, one I think they'll find hard to beat. Especially those of them who refused to sit on the bike and were attempting to turn the peddles by hand.
