I'm sure most people will respond saying that this is nothing new and that they have heard of this... blah blah blah
I don't care though, I'm sure there is atleast ONE person out there who has not.
Anyway, here is the recipe:
1 laser pointer
1 empty soup can with both ends removed
1 small piece of reflective glass (break a compact makeup mirror)
Syran wrap
super glue
rubber band
computer speakers
Carefully glue the small piece of glass (taking care not to cut yourself) to the middle of a piece of syran wrap and let dry. Cover one end of the soup can with the syran wrap, with the glass piece facing outward. Use the rubber band to secure the syran wrap to the soup can. Setup the soup can contraption infront of the diaphragm of a speaker. Setup the laser inline with the glass shard but slightly angled so the beam will reflect off the glass and onto a plain ceiling or wall. I DO NOT recommend holding either the laser or soup can as people tend to shake.
Now the fun begins... Once you are setup, turn off the lights and turn on some music. Try different songs. Some songs yield erratic laser modulation while others result in three-dimensionally rotating objects. There is a Pink Floyd song that gives a rotating figure-8.
NOTE: THE BETTER YOUR SETUP, THE CLEANER THE LASER MODULATION WILL BE. IF THE SYRAN WRAP IS TOO LOOSE THE LASER REFLECTION WILL APPEAR FUNKED UP. ON THE OTHER HAND, DO NOT STRETCH THE SYRAN WRAP TOO TIGHTLY AS THIS WILL WEAKEN THE SYRAN WRAP AND CAUSE IT TO BECOME LOOSE. AIM FOR A CORRECT BALANCE.
DO NOT USE TOO MUCH GLUE. DO NOT USE A LARGE PIECE OF GLASS AS IT WILL BE TOO HEAVY.
