This class used the red sets (motorized simple machine sets) to make pull back cars with 1 to 25 ratio
and now are trying out 1 to 27.
This car takes a thin rubberband. It comes back a little bit so it will be hard to do the
Chocolate Kiss contest.
Actually they did extremely well.
The Cities and Transportation sets can be used for many cars and projects.
