Making A Car Out Of Household Material ( preview on how to make it.....)

For my genius hour project I have created a car that is moved by a rubber band and is made up of 

household material. The material is a paper towel roll, 4 Cd's, 1 chopstick, a rubber band and colors to color it with. First cut the top of the paper towel roll. Then you need to poke two holes near the beginning of the paper towel roll and near the end of the paper towel roll and do that on the other side of the paper towel roll. Then you put the chopsticks through the two hole and connet it through the other hole, then do it again with the other hole. poke 8 water bottle caps in the middle and put four caps through the chopsticks, facing the way the chopstick ends. Do this all for all four chopsticks. Then, Put a cd on one end of the the chopstick so its touching the cap and put three more on the others chopsticks, to make wheels. Then put the other four caps on the other side of the CD and hot glue both caps on the CD. There are more steps but cant explain check out my car.
