I want to buy a laser that can pop balloons at maximum. This will obviously be >5mW but due to the rules of the house, 5mW is my limit. I was wondering if someone could place a "5mW" on eBay. I will pay the actual price but my limit is $40. I do not care what color, just what would be the most efficient for popping balloons. I realize the dangers, have eye protection, and know how to use it safely.
