"If you can vibrate your molecules, you can move through solid objects. Check this out." Bart said, zipping around the course to one of the large obstacles that was semi-circular and lying on its flat side, like a solid letter D that had fallen over.
Concentrating on speeding up the innate vibration of every molecule in his body, Bart ran straight through the object before returning to Tommy.
There were tiny yellow lightning sparks popping off of Bart's hair and the red lightning bolts on his cowl, but they disappeared once he stopped moving.
