Step 1: What You Need
~Wood (I used balsa)
~Small hinge and screws
~Spring (long thin ones work best)
~Rubber Band (Optional, to hold your laser switch on and to hold altoids tin together)
You will also need the following tools:
~Hot glue gun/super glue
Step 2: Screw on the Hinge
Attach the hinge to both pieces of wood so they can bend freely. Make sure there are still two holes open. They will be used later.
Step 3: Cut and Glue the Spring
Next, glue both of the strings to the laser. Do this carefully, making sure each spring can fit in the leftover hinge holes. You could even glue the springs to the hinge holes to make setup time faster.
Step 4: Enjoy Your Laser Show
You can take it apart and fit all the pieces in the altoids tin, making it portable and easy to move around. You can even fit it in your, I don't know, pocket?
When your laser is set up, there are many ways to create your show. Tapping things such as the tin, the laser, and the surface the tin is on make the laser move just enough to make a cool show. Gently shaking the switch on the laser (if your laser is like mine) also works, as well as blowing on the contraption.

Sorry about my poor filming skills on the video. I just simply tapped the board under my laser upwards to do it but there are many other ways. The more coils in your springs, the better and easier it will react.
