As kids, we used to make these as needed every summer, although occasionally someone would fashion a more elaborate one and keep it from year to year.
And no, none of us ever put an eye out with one of these. Then again, we were bright enough not to intentionally aim at the face. We also did a lot of target shooting with 'em. That's what I recommend: target shooting at cans or flies or plastic army men.
Wood - length of broomstick or dowel, or a 1"x2" or even a 2"x4". Whatever you use, you need a piece about 12" long (more for a 2"x4" rifle).
Clothespins - tradition says to use the wooden spring type, but the plastic ones will work just fine. The simplest gun uses one, we usually used at least two. They come in bags of 100 or more, so borrow from a neighbor if you don't have your own. Or make lots of guns, you politically incorrect brute.
Rubberbands - in our house, we kept rubberbands around the doorknob on the furnace closet, and had plenty because you got one with every newspaper delivered. They're cheap, so don't go mugging the paperboy for his.
Take sandpaper and round off any sharp edges to eliminate wood splinters. Use a file to cut a shallow "V" notch in the end of the wood. Use one rubber band to fasten a clothespin to the wood on the opposite end of the wood from the notch. That's it!
Here's a picture of a fancy store-bought model that works exactly this way. It's a good view of the clothespin and notch setup.
Hook a rubber band around the end of the wood so it's in the notch. Stretch it back with one hand, use the other to open the clothespin and catch the rubberband. When ready to shoot, press on the clothespin and zing!
You can cut out pistol or rifle shapes from the wood, mount multiple clothespins (and make extra notches), and do all kinds of custom coolness with the basic design. Often we'd grab a piece of scrap wood, use a rock to gouge out the notch, grab a clothespin from the clothesline out back and a handfull of rubberbands from the doorknob. Within minutes you had something that worked, and sometimes the ugliest thing was the straightest shooter (my best was a piece of old yellow broomstick with two clothespins attached). Showing up with a store-bought rubberband gun was tolerated - barely - mainly because we'd closely examine it to see how they managed multiple shots if it worked that way.
