Ah, back to being pitch dark while driving into work in the morning. I was actually making some headway with some light until DST showed up.
I've got an engineering question for you fellas. My 3rd grade son has a school project where the object is to make a water bottle roll down a ramp as slowly as possible, while still continuing to move forward. We can modify the bottle inside and out, but the shape must remain the same. I was thinking about glueing some shag carpet to the outside to create more friction. Any other ideas?
