[YellowBike] uber foam

[Joshua Marvel]

Actually. What about the idea of taking rubber tubing (like the medical tubing Aaron mentioned,) bending it into a circle-y shape and filling that with the foam. it would be easier to avoid the lumpiness, I think. And would hold its shape better.

i think using tubes is a great idea for the foam, if we just bought
schraeder valve stuff and pulled out the valve bodies).
