In science, we made a long chain with different materials and then we tested it with different weights to see if it doesn’t touch the ground. (that probably doesn’t make sense.) sorry.

Which Part will work the best and why?

The pipe cleaners will work good because they have twisted metal in the middle and will be really strong.

Which part might be a problem and why?

The paper rings I think might snap, the tape isn’t very sticky.

Why you did or didn’t use some of the materials?

We didn’t use the rubber bands because they would be too stretchy and the bottles would touch the ground.
