We’re pretty sure there’s no real use for this Magnetic Accelerator Cannon, so banish any Large Hadron Collider thoughts from your brain. You stick a ball bearing in one end, and some sort of magnetic jiggery pokery shoots another one out of the far end. Stat. Nope sorry, this is highly unlikely to get you a girl or boy friend. $29.99.
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. The Magnetic Accelerator Cannon 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).
