As it starts the wheels shove the stick forward ahead of it. Pink thing will just barely beat the ball there.

Wow, your tube walk solution was much simpler than mine. I used a stick on the bottom lip to hold my rig up while it got ready, used a couple of sets of wheels on each side with a wheel and rods attached in the middle to force the side wheels into contact.

It was a bit of a mess, took a while to fine tune but worked in the end.

Sometimes the KISS solution is the best -

Sounds like yours is what I was trying early on. Actually what I used HERE in the U-turn was from one of the first designs for the tube.

Fun little game - wished I had saved all of them.
