Have you ever wanted to have a light saber battle with your brother, yet don't want to get beaten with a plastic stick?
Go no further than laser pointer light sabers, the closest thing to the real thing!
Step 1: Materials
You're going to need a couple of materials for this to work.
As many laser pointers as people using them
Lysol or some other aerosol spray
Step 2: Have Fun!
Turn on your lasers and begin to spray the Lysol.
Instead of having an "invisible" beam, the photons will be visible and reflected off of every spray of the Lysol.
It's just like having your own light saber!
