I stole the title from one of my favorite Talking Heads song/video.
A little background here. My youngest son wants to participate in the 2012 Science Olympiad. He and one of his friends want to build a trebuchet. I agreed to help, but only with the construction, the design had to come from them.
The axle for the throwing arm is 0.5″ threaded rod which had to be cut to size. I let my son do the cutting using a pneumatic die grinder, which is an abrasive wheel spinning very fast. As he was cutting, I was seeing sparks and photos.
After he was done cutting the piece he needed, I took the left over and clamped it to a stand. I covered the stand with my trusty black cloth. I took this photo of the setup with my cell phone.
A contribution to Macro Monday. I’ll be away for a few days, so I might not get to visit.
Here’s a close up where you can see my hand holding the grinder against the rod generating the sparks.
Here’s another without my hand in the way.
