This is the last LEGO project for the year at Ona.
We are using pulleys to make a crazy dancing floor.
The 8 tooth gear and the crown gear mesh at right angles.
We learned which way to put the crown gear so that it will mesh.
The pulleys can make the motion the same way or opposite.
We get to try out different size pulleys.
The pulleys can make the sides move faster or slower.
