Newton's 3rd law states: For every action there is a opposite and equal reaction. In pogo sticks, when the spring condenses and gains all the potential energy, it releases all the energy, and it's kinetic energy sends the pogo stick flying up. The energy of the spring is equal to how high you jump.
Let's say this: You are jumping on a pogo stick. Your mass is 90kg, and the acceleration due to gravity is 10. Your pogo stick weighs 5kg, what is your total force?
The Maverick is the next step up. It is for beginners and is a true pogo stick. It comes in three color combinations, black-silver, silver-blue and red-blue. It is recommended for ages 5 to 9 year olds. Weight recommendations are 40 to 80 pounds, but some users say an 80-pound child may be a bit heavy and bottom out the pogo stick. This toy has consistently high ratings from reviewers. The metal frame is foam covered, the foot pegs and handles have rubber coverings to prevent foot slips and firm hand grip, and the tip also has a rubber cover. It comes in several colors including black and silver, green and black, and blue and red.
