Magnetic Accelerator Cannon
ThinkGeek is back with their Magnetic Accelerator Cannon which will play on the laws of Newtonian science, where it will definitely be something kids won’t mind checking out if they have a budding scientist’s mind. After all, it really isn’t that hard to put together, and does a pretty great job at illustrating what a magnetic accelerator would look like. It can be ready and armed within minutes without the need for any glue, and would make for a decent candidate at science fairs or in the comfort of your own home. Each $29.99 purchase comes with 10 metal balls, a loading tool, necessary instructions and half a dozen barrels for you to shoot.
