Re: I've gone green!
Well done for trying! I am a science teacher and would like to get my students to try these things but all they are interested in is the van der Graff generator and any chemistry experiments that go "bang!". I am going to run a "gifted and talented" club from September.
Today I was teaching year 7 (11-12 year olds) about cells and batteries. i demonstrated by showing an old vidor portable radio and connected 10 9V batteries in series for the HT battery and it worked! they were amazed at the 50 year old radio and asked several questions about how the valves worked and why it needed such a high voltage. I hope I got 1 or 2 interested!
