You know that's a good idea, because the camera sees IR, and people will understand stuff they see better. ;D
You can also try an effects video with diffraction gratings, crystals and stuff, lenses, lots of fog, diffraction gratings+crystals and/or frosted glass, mirrors, spyrograph, and stuff like that!
You can shine your most powerfull laser , focused through the spyrograph on a piece of receipt paper and see if it draws the pattern
Detonating homemade bombs at long range using lasers and beam expanders.
After you get another blu-ray you could make a flourescence and GITD video where you line up all these minerals and plastics and glow-water and gitd material and shine your bluray along with your camera moving across the "line" of reactive stuff and show different pretty colours and glowy goodness.
Use the IR laser and a nightshot camera to illuminate stuff that passes IR and compare to normal visible conditions, like a glass of coke
Do the gunpowder+TNT bank idea, take some money, buy an RPL 425 and make some videos of that :
