Back to B.C. by Johnny Hart for May 11, 2019

Try bouncing off a tree.

It must hurt, when it rolls over his forearm.

That’s Easy! A “straight line, and sudden, VERY abrupt STOP!

I think……, ;)

It occurs to me that we have B.C.-type transportation today, in hoverboards. And the turning radius is also effectively zero.

There are even one-wheel “hoverboards”.

Finally, a return to the good ol’ days of B.C. :)

…. and if the wheel scrapes the skin off your leg.

“Today on our continuing store-y on ‘As the Wheel Turns’…”

So the wheel can bounce off walls by itself; my wife will be so-o-o happy…

Body English. And physics.
