I tried it, my car flipped upside down and floated up and got stuck in a tree.
Actually it would be expensive since the helium would easily leak like it does from a balloon, would you want to fill your tires all the time?
Coarse edged youth, the irish pendants string from their smiles
not yet plucked as to slacken the seams
and drag down the features of age,
no folds or creases from unkempt wear
eyes of tranquilty, crystalline-beads
no sign of despair in their hair, nor their hearts
but oh they have yet to be experienced and that makes aging so very worth it...ML circa2012
