Here's a pdf for you today of an old fashioned book - Gilbert Light Experiments For Boys.
It's by a professor of physics, Carleton John Lynde, Ph.D.
It's from 1909, so it's called "For Boys". :)
Along with discovering light, illusions and a few other things are explained.
It's quaint, but interesting.

That is so cool! And we can learn about how common sexism was back then, too. So it's a good history lesson as well.
