How do you make a laser pointer? Or one that burns through stuff??

I think kipkay did a video on that... http://kipkay.com/section/videos/lasers/

He's done a bunch of videos on how to make burning lasers! I think you can use a blue laser from a DVD writer or Blueray reader as your diode... Be careful if you try this; you might blind/burn yourself!

A laser pointer is a 5mW (milliWatt) laser diode/laser LED connected to about 5 volts/3 button cells. You need over 100mW to get hot, and that's just barely enough to pop a balloon.
