Testing and Troubleshooting.
Create a small curved corner in the left corner of the box by cutting some cardboard and block out space with Play-doh to prevent the balls from rolling into the corner.
Add rubber feet to the front of the box on the left and right corner to tilt the box. This will help the balls roll towards the wheel (canister top)
