Baby.
One day, when we have kids, I have a GREAT idea to teach them how lasers work.
You dress up in a big round electron suit, and I dress up in a big (but smaller than yours) photon suit, and we have to act out the whole thing.
We can make a background of all the parts of a laser first.
Like the diode, and the driver, and the batteries, and THEN we have to make a song to make it easy for them. That way instead of going to school and singing the gay alphabet like all those other 1st graders, our kids can sing songs about the electromagnetic spectrum, and the different frequencies and wavelengths of each color laser. :]]
