It is hard to see the last gear moving but it is.
This snail car goes slowly.
They figured out that it takes
3,375 rotations of the axle on the motor
to have the axle on the wheel go around 1 time.
A drill can use gearing.
Still going
Drill goes fast.
Owl is done.
Almost the end of class.
Owl is programmed.
Still going. Actually it took 34 minutes to do 3,375 rotations.
