Switch Sunglasses Arms

I came up with this idea when a friend's sunglasses where broken, but the did have nice arms. so I screwed them on an other pair of glasses and created this nice look. its really easy you actually don't need an instructable for it.

Step 1: Materials

You'll need:
-2 pairs of sunglasses
-small screw driver

note: make shore that the sunglasses have the same attaching system so the arms can be switched.

Step 2: Screw

use the screw diver to remove the legs of the one sunglasses and attach them to the others. and your finished.
