This is not about repair, but I thought someone on here might know.
Those little laser pointers that kids play with. What happens if you
shine them directly into your skin, such as a hand. Is that
dangerous?

Not in the least, as long as the laser power is in the = 1
milliwatt range (most of the consumer pointers seem to be).

more powerful, but I still wonder about these pointers. One of the
kids keeps doing it, and said it makes the spot warm on their skin.
So I took the thing away from them. As a test, I pointed the thing at
a spot on my hand, and they are correct, it does make the spot warm.
That makes me more concerned about it.

You needn't worry. I have a similar pointer that I've shined on my
own hand for minutes at a time (as an experiment). It never gets more
than just warm, 'cause it doesn't have enough power behind it to do any
real damage.

Now, with that said -- Emphasize to these kids that these laser
pointers, though they may not be powerful enough to harm skin, WILL
cause permanent damage to eyesight. NEVER stare a laser in the eye,
period!
