Create towers as tall & strong as possible and test til they're destroyed
Bamboo sticks (some of which will break) & string
Strong plastic bags
Weights (bottles of water etc)
The scouts must create a structure that holds the bag as high up off the ground as possible within a set time.
When the time is up - the height of the bag is measured, and then weights are added to the bag, one at a time, until the structure collapses.
Points are calculated by the number of weights multiplied by the height rounded to 10cm.
Two weights in a bag 14cm off the ground = 2 x 10 = 20 points
One weight at 39cm = 1 x 40 = 40 points
