James' Impossible Bridge

The Impossible Bridge

Problem:  I wanted to make a bridge.

What I used:  String, tape, straws and cardboard.

What I did:
·    I got a strip of cardboard;
·    I taped straws under the cardboard;
·    I made 2 long straws to put  on each side;
·    I made the uprights;
·    I attached the string.

What I found out:  I discovered that a suspension bridge is a strong bridge.

  1. Your bridge looked way stronger than the other kinds of bridges.
