Doctor Campbell’s Science Demo

This is a video podcast. Please subscribe via Doctor Campbell's Science Demo on iTunes

These are a series of short films demonstrating basic scientific principles. Some of them are thinly veiled excuses to muck about with fun stuff but it is all valid. Most of these are hosted on and a few are m4v compatible files that play on video iPods and in iTunes. If you have any suggestions for future demos, please drop me a line at
