The Unstoppable Wheel

this is one very neat invention that was just made by fooling around with knex. This amazing vehicle is basically unstoppable when you tip it on its side, it filps back right. If it hits a wall it turns itself. Just build and see!
Happy Building. And Merry christmas too.

Make two of these. These will be the wheels.

Add 6 spacers on one side of the motor on a gray rod and a red connector on the motor. Then do the same but with 5 spacers on the other side.

you can add wheels on the red conectors but it makes it less fun (in my opinion)
