One day I went to a science competition where they were testing out a size macine. The first thing they did was that they tried to shrink a tennis ball. After a break they tried to make it bigger. As they attempted to make it bigger instead of shooting the ball like it was suppose to it shot the next scientists prop, a trident. It made the trident so heavy it broke the concret and fell partly into the hole it had made. Later on the scientist with the trident called jack admited to changing the settings and was banned from the competition.
