I once again regret volunteering for things and then going overboard with execution. We have a Cub Scout Day Camp that will run the next three days. I work with the oldest boys, but offered to help with the Wolves as there was a lot of crafting and woodworking involved. Being the idiot I am, I went for much more elaborate than needed projects to meet the goals. Camp is always fun so I hope that makes it worth it.
The requirements I’m trying to meet deal with vehicles and physics. They are required to build a car that moves on it’s own power, two different boats, and several differently shaped paper airplanes.
I decided to show different ways they can power a car without the use of a motor or their touch. Balloons, Rubber bands, and Springs were the three that I can up with.
The spring car was poorly thought out. The spring is way too close to the axle that it is connected to by heavy thread. The car should have been much longer.
The candy box cars with balloon engines travel the furthest of all. The kits for the boys have different types of wheels. The wheels were pinewood derby wheels, plastic bottle caps, and CD’s.
The wheeled boat and rubber band cars are the same in theory. Both involve twisting a rubber band taut and releasing it.
The simple boat has a hole drilled through it to allow a 1/2 inch diameter plastic hose. Balloon on one end, the other is for blowing it up and putting it back underwater to power it.
The paper airplane launcher was simple. The planes are hole punched and fitted with paper clips to attach the plane to the runway.
