A foot pump is a lever.The foot pump allows us to use our legs to pump vehicle tires,inflatable toys , athletic balls and more!Using our leg to pump a ball is easier than using our hands.The foot pump has an air pressure guage which lets us see the air pressure of the object that you are pumping.The further the effort from the fulcrum the lesser the effort is needed to push the pedal down.The foot pump has a base to help support it.
