Design
Traditional pogo sticks use a metal spring to create bounce. Air-filled pogo sticks -- made from either lightweight plastic or aluminum -- compress air within the body of the stick to create pressure, using an air cylinder/piston combination. Jumping moves the piston upward, compressing the air; when the pressure in the tube becomes greater than that of the rider, the piston reverses and sends the rider high.
Use
Before using an air-filled pogo stick, you must fill the tube with air, using a bicycle pump or an air compressor. Vary the amount of air you put in to create more or less bounce pressure.
Advantages
The materials used to make air-filled pogo sticks make them lighter than traditional models. Air-filled pogo sticks also create a much stronger upward force than traditional pogo sticks, sending riders 6 to 7 feet in the air. Adjust the amount of air pressure in the tube for weight, less-experienced riders or those wanting a higher bounce.
