Probably you have seen some of James Bond’s movies and his laser gun. And probably you wanted one just like that and you didn’t have a place where to buy it from.

We can show you how to build one yourself. You need a plastic gun and a blue laser diode. The expensive part ( but not very expensive) is the diode.

You can even pop some balloons with your new laser gun. Or light some matches. I wonder what other tricks you can do with this gun because the laser can make a surface really hot.
