I wanted to take my "W" concept one step further and construct a slingshot that protects your fingers from nasty slaps.
The idea: To use steel rods that are not strong enough for a power slingshot, and form a grid that stabilizes the device.
It shoots fantastic. My favourite right now!
Since it works so well, we have election day in our state (North Rhine Westfalia) and the German eight rowing team won the World Championship, I chose our national colors black, red and gold (OK, yellow).
