Pupils at Whitminster C. of E. Primary School test out the balls they have made out of plastic bags and string after learning that this is how the children of Kigulya village make their own balls.   The Whitminster pupils discovered that these balls can actually bounce if tightly made, but that if the string is not securely knotted into a form of net, it will easily unravel and the ball will fall apart.   Their admiration for the skill of the Ugandan school children increased measurably through this exercise!
