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.
