Do try this at home

A quite interesting link from my friend Jigar, about a series of videos showing how to make interesting experiments at home using ordinary materials. However, some of the experiments are not quite easy to reproduce, especially the ones that involve drilling wood, since not everybody has the tools to do this. In any case, the paper jet engine looks like an awesome thing to do at a bar, though blowing in the hole as Mr. G. says is not as easy as it looks.
