Madzhid & Sina straw bridge bulding

Our bridge must contain 50 straws, not less, not more. Its length should be exactly 20 cm. Sina and I are working in one group, we are partners in the task that we should accomplish. We need the following equipment:

• Scissors.


• 50 straws.


• ruler.


• sticky-tape.


• two objects (to place the bridge between them.

Sina and I are using strong bridge building method which is to build a bridge that absorbs the pressure all over it, so when a heavy object is placed, the pressure distributes on the whole bridge, and the bridge becomes able to hold the heavy object e.g. book, dictionary.
