How come it’s easier to blow up bigger balloons than it is to blow up the small ‘water balloons’?

You would think that our lungs, that have stronger muscles and more air capacity, would be able to push air into that tiny thing and make the smaller balloon expand, but the slightly bigger balloon is way easier.

It’s all about the pressure we can exert. The air in the balloon exerts pressure on every square inch of the interior of the balloon. When the balloon is small, a bit of pressure applies very little force, as there are almost no square inches there to push on. A large balloon has a huge surface to push on and so the force is great, despite the pressure being the same.

Water balloons are usually thicker than air balloons (because they need to handle being full of dense water rather than decidedly less dense air), which makes them harder to inflate.

The size of the balloon doesn’t really matter, what matters is the strength of the rubber. A water balloon just has to be stronger to hold the water.

It’s worth mentioning that our lungs are designed to suck, not to blow. We can suck air with a much greater pressure than we can blow it out.
