Rookie Team 4946 Shooter (Wheel material)

[Qcom]

Last year, our team took some andymark pneumatic wheels, took out the inner tubes, and put in some pool noodles. Worked like a charm, and remained consistent without having to be reinflated constantly.

I don't know how it would fair with an excercise ball (this year we opted for a pneumatic launcher), but it would be something worth testing if you think you have the time.
