What is the World's Record for the most Ping Pong bounces? My friend and I are trying to see if we can break the world's record for the most ping pong bounces between two people.

An example of the ping-pong mechanism would be the action of chymotrypsin. When reacted with p-nitrophenyl acetate (A), the reaction of chymotrypsin is seen to occur in two steps. In the first step, the substrate reacts extremely fast with the enzyme, leading to the formation of a small amount of p-nitrophenolate (P).
