This is a cranky contraption I had made during design class. It tells

the story of a jumping slime.

  1. My biggest success was making the crank. This is because when I first made my crank, it was very smooth and it worked very well.
  2. My biggest obstacle was making the slime stay and not turn every single time I crank it.
  3. One thing I like to change is to remove the black cardboard covering the whole top.
