Wind Power

Wind Power

This experiment is closely related to the potato-powered mp3 player but not the lemon battery, so if you try this at home…well…

Anyway, the set up involves a lighted candle, a couple of screws, a glass jar and lid, various crocodiles clips and wires, and a small motor with a fan. Put them altogether, break wind into the jar, and power up the electric motor. It’s a slow burner this one…

The trailing wire (as with the disconnected sweet potatoes) may provide a clue as to the nature of this experiment. Moreover, if you watch carefully at two points during the clip it becomes fairly obvious what’s going on. Any suggestions regarding scientific reproducibility in the usual comments box below, please.
