We have a laser at work for evaluation. The output is 8 Watts of 532 nm coherent collimated light (this is a lot of energy, it can easily vaporize metal). It’s only going to be here for the next couple of weeks, so I’m trying to think of awesome things to do with it after-hours. I’m planning on at least playing with water, food, and combustables. Perhaps I’ll make a laser pen.
Please submit your suggestions in the comments! I’ll try to make some videos, but no promises.
