The materials I used in this design were:

 

  • Rocks
  • Fabric
  • Fabric with holes
  • Tube
  • Plastic bottles

I think engineering is important because when you’re really in some trouble, you need to know how to solve your problem.

Something challenging was actually making the structure stay and making the rocks not flow out with the only ducktape and ribbons.

We choose to make this design because it was simple even though we could do better, something I want to change is putting cotton because there wasn’t enough cotton.
