"You will hit your hand". I know the fork is low, but of course I won't hit my hand with it.<br>The rooftop slingshot, a far more dangerous design, really hit my hand. Or, rather, I did, not using it correctly.<br><br>But a normal fork is a different issue. In order to show the safety, I made a version of the hammerhead that has a 40mm "wall" above my hand. The fork is only 25mm high! So it seems impossible that the ball can fly over the wall.<br><br>And yet it works. Flipping does that. The safety margin is a good 100mm.<br><br>Will show it in a video soon!
