Appliances that work on air pressure: 1. Syringe Explanation: When the piston of the syringe is pulled, the volume in it increases, while the number of air molecules is still the same, resulting the low air pressure in the syringe and automatically, the air pressure outside is higher if compared to that of the air pressure in the syringe. the higher air pressure outside will force the liquid that you wish to suck to enter the syringe. 2. Siphon (for cleaning water in the aquarium) 3. Spraying pump 4. Straw All of the appliances work according to the same principle.
