CNI Portable Green Laser - PGL-III-C 532nm at 500mW, popping 23 balloons placed in a row. Notice the bits of rubber flying in the air. I used a masking tape to hold them to the floor so they don't move and placed the laser on several books so it also doesn't move. The farthest balloon is 6 meters (19.5 feet) from the laser. The music is Beethoven 9th symphony, I thought it fits the plot. The crackling sounds at the end is the masking tape peeling off the floor. Edit: To all those interested in how I got it and how it cost - go to laser pointer forums (google it), and see the group buys section, and you can also find reviews there. Edit: I have a new movie here: http://www.youtube.com/watch?v=TXzCIKvXeq0
