Kaiana's Impossible Bridge

The Impossible Bridge

Problem:  I wanted to make a bridge.

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

What I did:

·    I got a strip of cardboard;

·    I taped straws under the cardboard;

·    I made 2 long pieces to put  on each side;

·    I made the uprights;

·    I attached the string.

What I found out:    It was the strongest bridge.
