See EZBREEZY™ in Action:

Effortless Inflation & Deflation for Pool Floats & Inflatables

Use the built-in hook to lift and pop the valve stem open. Clip EZBREEZY® onto the valve to hold it open hands-free. Blow air straight in - no biting, no dirty valve in your mouth. For deflation, it's just as easy. Clip it on and walk away while the air flows out on its own - or squeeze with both hands to push it out fast. For floats with more than one valve, clip one onto each valve at the same time so all the air flows out simultaneously for even faster pack-up. No batteries. No awkwardness. Just easy.
