This is a cool activity we did in class this term together with our buddy class. We were presented with a technology challenge where we had to use 20 sheets of newspaper, 2 rubber bands and one metre of string to make a device that would fling a ping pong ball as far as possible. Here's one team's construction. I think from memory that Jayden and Jack Sproull's team won. The ping pong ball went about 3 metres!!
