"Thermal experiments with a 150mW Green Laser"

You could demonstrate lighting matches and popping balloons with your X125, you could also show that it pops black and red balloons and it doesn't touch white or green balloons and you could explain why that happens.

Build a 3W IR and demonstrate it's blinding capabilities on faculty.

No just kidding.

Build a bluray, a red, and get a green and demonstrate fluorescence, visibility vs. wavelength, burning power, or refraction all while riding a unicycle.

lol @ while riding a unicycle ;D ;D ;D

Yea, chances are you wouldnt be allowed such a high power laser at school. Try gathering up a BR, red and a lower power green, do some colour mixing and flourescences as RA_pierce said.

The teachers should let you bring in a high powered laser if you tell them your project before hand. Heck I made a bet with one of my teachers that my "laser pointer" could light matches and pop balloons and he let me bring in the laser. I one a nice cold can of Spite. ;D

bring in a low powered HeNe or something like that. That would be neat and low power at the same time!

Yeah, I would say the easiest cool thing to do would be demonstrating the popping effects on like black and red balloons compared to white ones, and explain why.

Fluorescence with a blu-ray would be the best. You can explain why, which will take you some time if you explain EVERYTHING.
