Dave, we call it Screaming Jelly Baby's over here - "Jelly Baby's" are the sweets we use. I have done this a fair number of times and I always just do it with a clamp and stand. Will have to consider putting it on a bearing and doing two opposite each other!! I have a couple of chemistry related videos that my students put together for me over on my youtube channel. Sorry about the music selection!! http://www.youtube.com/user/craynerd Have you ever tried to introduce any other engine related projects or activities? I have been thinking about Stirling engines under the topic of "energy resources" but that is lower school and I think tin can stirling would only be suitable for older higher ability. I have just finished making a tin can Stirling to see how it works and have managed to get a runner but it has taken time! Thanks for your post. Chris |
