Extra information about process:

This video displays me and my teammate testing the G-streak using battery power.

Here are some pictures of the process for building the car:

This picture shows me and my partner spray painting the G-streak balsa wood.

This picture shows me measuring the pieces of balsa wood to cut with a multi-use tool.

This picture shows me putting on a piece of wood to help support the solar panel using hot glue.

This photo shows me and my teammate putting on the axel holder to make sure it is strong enough to hold the axel because if it flies of during the race it wouldn’t be good.

This photo shows the electrical schematics of the car which includes the motor, battery pack, and solar panel.

Using google, our team was able to figure out why the wires would get so hot when they would touch. When the wires touch, they create a short circuit, which causes a large energy flow that creates heat.

Here is a cool video of the G-streak spinning so you can see all sides.
