This is one of the spring cars that my group built in Engineering 100. Notice the high tech shiny foil covering the wheels.

Not only does the sunglassess case and a roll of sticky tape act as counterbalances in the design, but they add a distinctive "coolness" not shown in the other cars.

This is the second revision of the "Pink Rocket". The first model was too heavy, so we changed the sunglasses case for a stylish glue stick. I'l post more pictures as we make more revisions.

A nice double rainbow.
