One of our readers sent in this interesting project. The Sun Gun is a device that allows you to see the sun without melting your retinas. This looks like a cool project to make for the kids.

I wanted a solar scope, safe and portable, for group sun spot viewing. The designs I looked at did not lend themselves to group viewing, or the safety I wanted, especially with children. After many hours at the hardware store I designed the SUN GUN.
