I do the science demonstrating, but this week I'm letting two other science demonstrators show you their all time favourite science tricks. The first demonstrator is James Piercy of Inspire Science Centre, Norwich. James's favourite demo's are both food related - the incredibly dangerous glowing gherkin and the explosive liver rocket. Click on the picture to watch the fun. Do not attempt to perform the glowing gherkin yourself.
Mains electricity can kill.
Make sure that you wear eye protection if you try the liver rocket. My second demonstrator is Mike Hoyland from the Chemistry Department of Leeds University. Mike loves to make his chemistry bark like a dog. He also makes miniature volcanoes and glowing 'snow globes'. See how he does it by clicking on the picture.
