BitMobile

Being a tech kind of guy, the next year made the BitMobile. Note the wheels now have hub-caps, which keep the wheels away from the car body. These are made from photographic paper with the shiny side in, glued on with super glue with graphite inside the hub. Just the rounded head of the axle(nail) rubs on the inside of the hub cap – very little friction. Think about the theory and you’ll get it. This car was much faster than the BatMobile. Notice the front of the car is sloped downward from top to bottom – this makes it so the top-most part of the car is the only thing in contact with the starting gate. The starting gate is usually a wooden or metal peg which comes up through the track, and holds the cars in place until it pivots down toward the finish line and disappears under the surface of the track. As the starting gate is lowered, the top of the gate moves faster than the bottom (think of a lever) and since that is the part the car is in contact with, it gets off to a faster start. Think about it.
