Bridge Revise

Problem: To construct a strong bridge that can hold 2 duct tape for 1 minute.

Materials: 2 A4 paper, 10 straws, 1 pipe cleaner, 1 cardboard roll, 1m tape, 1m string and scissors.

How to make it:

* We cut the tape,string and cardboard roll.

* We  measured the cardboard roll, rolls have the same measurement and dimension..

* We connect the cardboard rolls with sellotape to the base.

* We stick the string on the straw with sellotape and we stick the sellotape together with the cardboard roll.

* We put tape on the string and cardboard roll.

* We tie the string together with the straws.

* We fold the paper on the sides to make our rails.

* We construct our bridge to make it sturdy and stable.

* We bend our straws together.

We tested the bridge by placing 2 duct tape on top of it for 1 min. Our bridge held the duct tape but then it fell down. However when our bridge collapsed we reconstructed it again. We tested it out again with 2 duct tape to see if it holds and it did!

It was a success, the duct tape stood for 2 mins and the bridge did not collapse. We were persistent to go on and never gave up. We collaborated in the building of our bridge.
