How to Make a High Power Laser Pointer
Laser pointers provide a beam of laser light, but the intensity varies depending upon the cost. Laser pointers sold in drugstores and supermarkets have had their intensity adjusted to where the laser light generated is nearly nil.

A few common hardware tools are all that is needed, as is about 10 minutes of your time.
