First things first: we do not advise you to try this at home. Or in a field near to your home.
And now that we've got the health and safety announcement out of the way: sit back and chuckle at the 'wait for it... wait for it...' charms of the little video above. Which proves... well, how electricity works. And how silly teenagers can be. Bless!
Still, anything to get them interested in science, eh?
