Re: The physics behind trackball inflation
well in theory with the added weight of the skin any air on the inside would be compressed past 1 atm (~14.7 psi) (PROOF: unplugging a partially inflated ball will still deflate signaling that the interior pressure was greater then the exterior.) so any inflation would add mass, but should be negligable till ball reaches maximum volume, dictated by the material's elastic constant.
(I always love myself a good debate  )

Anyone can watch Westcoast Choppers and see adults build things, but FIRST is great because it encourages kids to do the building and adults to do the watching.
