P. T. Selbit's Cheese Wheel

Origin
P. T. Selbit was the first magician to perform the famous sawing a woman in half trick. His inventiveness made him well known to audiences and fellow performers for his ingenious little tricks. One such spectacle was “The Mighty Cheese”, a seemingly large cheese wheel that seemingly defied logic and stayed oriented on its side. Any challengers who tried to push it down all failed, as it would only move out of the way or fling opponents backwards. The wheel was actually fabricated out of metal, and inside it contained a gyroscope that spun and kept the model upright. The trick was not well received and Selbit passed it on to other magicians, who had the same amount of luck with it.

Effects
When moved onto its side, it will stay in that position until lifted up from all sides and placed face down. During its balancing act, it will constantly leave the vicinity of people to be alone. Anyone foolish enough to knock it down will instead be knocked themselves. Violent movement will cause the ground underneath to suddenly buckle and pop out from the rest, shooting the cheese and perpetrator in different directions.
