The AIMS Magic String project from Brick Layers II
seem to make a string grow.
The 40 tooth gear and the 8 tooth gear mesh. Pulling the long string on the axle with the 8 tooth is easy.
Pulling the short string on the axle with the 40 tooth gear is fast but hard.
Two made a conveyor belt and two made a merry go round.
Then they showed their projects to their principle.
See how long my string is.
