It is not so difficult to have your home laser show.

The idea of having your own laser show can seem a bit far-fetched, but just think about how cool it could be! It may sound hard to build, but an inventor named Geoff Milburn has come up with some easy instructions.

By using materials like a lab style laser, a diffraction grating, an old pair of headphones and a few electrical parts, the device can be fairly simple to put together. All you need to do is to be able to wire a few things here and there and also do a bit of soldering. But before you start, you should make sure to read up on laser safety.
