How The Air Comes Out Of The Nozzles

The air comes out of the nozzles the button to turn on the nozzles is on the button wall but i am not talking about that i am talking about how the nozzles gets its air it is the same thing as how the water gets in the rocket the same way but you have to use a pump but the pump that i am talking about is not the pump that pumps up the wheels it is a different pump it is a pump that is for the nozzles but you now how to put the water in but you put the air in a different way because when you put the water in all you have to do is put the water in a hole but when you put the air in the air you have to put the air in side of a bag but with the water you just put it in the hole. To get the air you have to pump up a bag and then put the bag in side of the hole and then that is it.
