Experiments with laser pointers?

What fun things can you do with laser pointers?

Maybe some experiments? Any fun things?

Just write whatever comes to mind.

Please do not suggest glare from airplanes, cars, trains, etc. or glare in the face or annoying the cat.

And above all, please no moralizing spam like "laser pointers are dangerous" or "why do you even have one of those things? You could go blind quickly."

My cats go on and you can play with them for hours.

This has nothing to do with annoying.

It depends a little on the age of the cat. Young kittens are often frustrated because they chase something, but have no success. Older cats eventually understood that it’s just a game.

Right. My cats are older and know exactly. Nevertheless, they go along and chase the red spot until they have no more bock.

You can try to find out the quantum physics properties of the light, which are pretty cool. W laserpointer
