We started our Inane Innocuous Invention Convention Project for 2012. Today we began building our inventions which are our own Rube Goldberg creations. Our invention must accomplish a simple everyday task and can not use batteries. We introduced Newton's First Law with a couple of demos:
Place a vase, metal pie pan, cardboard tube and egg in a tower. Quickly knock the pie pan horizontally and this should cause the egg to fall in to the vase. Egg Drop Experiment.
Inertia Rings balanced on top of a plastic soda bottle and then a small hex nut balanced on top of the ring.
We all tried grabbing the ring and allowing the hex nut to fall into the bottle.
