Kilograms are currently marked by a cylindrical lump of platinum and iridium known as the 'Big KG' in Paris, but scientists are seeking to redefine it by far more, well... scientific means.

Labracadabra, a series of science videos and experiments from the folks at GE, may be designed to get you interested in the work that the company does, but they're also a look at some fun chemistry and physics experiments you can do at home -- with great results.
