Year 8 pupils set fire to a teabag on top of a £20 note.
A neat trick that’s also often done with the wrappers for amaretti biscuits, those delicious almondy things made from apricot kernels that you get in fancy Italian restaurants.
Here, a humble teabag suffices.
As with all experiments involving fire, do this only with adult supervision.
Winner: Best Presenter, 2009
This is a deceptively simple film. A static camera, clamped on a tripod; a straightforward (though unusual and impressive) demonstration; a tidy explanation. It’s completely made by the performances of its two presenters, which lift it from being a competent but unremarkable SciCast film, into being an Award-winner.
