the contest start when the "jockey" positions his or her frog and then yills , screams , jumps up and down, puffs, blows, whistles, or does whatever else in neccessary incite the frog to jump. the one thing that is not allowed is any kind of physical contact with the frog. Each frog is given 15 seconds to jump three time. Once a frog has made its three jumps, an official measures the distance from the center of the pad to the spot where the frog landed on its third jump. Naturally, the winning frog usually the one that jumped in the straightest line rather than zigzagged around . Some frogs frustrate their "jockeys" by jumping back toward the launching pad after a apectacular firsts or second jump.
