Why exercise balloons slowly debunk?

That thin wall of condom that keeps in the air and your kid delighted for upward of 10 minutes is airtight, which is how it keeps air inside and the balloon properly inflated, obviously. But it's not completely or perfectly airtight. Equally the surface stretches to inflate, the surface becomes so thin in some places that tiny, microscopic holes result.

Air molecules are able to slowly diffuse, or escape, via the surface of the balloon, or tiny holes in the know y'all tied to go along the darn affair closed.

This process of boring air leakage isn't so slow with those shiny, fancy, helium-filled mylar balloons. That's because it's easier for helium to escape the balloon than it is for regular air to escape regular plastic balloons. Helium exists as a unmarried atom, so it's smaller and quicker, if yous will. That air yous breathed in bonds equally ii or three atoms (and of different elements, including carbon dioxide). Those cause a jam up in the escape pockets.

Only if air tin leak out…doesn't that hateful that air can also leak in, and re-inflate the airship? It could, but it doesn't. The air force per unit area is college on the inside of the balloon (because of the surface of the balloon badly holding all that air in i place).
