Make Your Own Laser FlashlightS

If you liked that backpack laser we showed you the other day, here's a much smaller laser that you can build yourself using an old DVD burner and a MiniMag flashlight. It's not going to be anything lethal, but it can actually cause a bit of damage, lighting a match or even popping a balloon with its ray gun-like beam. If you're slightly mechanically minded, you just might be able to put this one together. Be careful, though, you could put an eye out with this thing. In case you missed it, see the awesome video on the next page.
