Magnetic Accelerator

This nifty magnetic accelerator kit from ThinkGeek “is a great study for science fairs, but is just at home on your desk (just be careful what it sits near – these magnets are STRONG).” Video after the break. Click here for first picture in gallery.

Set the metal ball at the end of the track and watch as the energy transfers and multiplies down the track of magnets and metal balls until finally the last ball zooms off.
