How well did the racer work?  Did it go far?  Did it go fast?

The racer went pretty far for just a spool and rubber bands. It didn’t go that fast but I went the farthest in the class. But it worked and I didn’t think it would work or go far.

What aspects of your design are working?

When we tested the racer all of the aspects worked except for when we rolled the rubber bands they got in the way of the racer moving.

What aspects of your design are not working?

When we rolled the rubber band around the Spool.The rubber bands got in the way of the wheels turn in that slowed down the racer.

What questions do you have?

Ome question I had was how can we roll up the rubber bands in a way that the don’t get in the way of the weels don’t get in the way.

How will you adjust your design?

Maybe I’ll can shorting the rubber nbands so they don’t get in the way of the weels.
