I tried it, sometimes it hangs around there for a while, and does nothing.
Other times it flies away into the wind and you don't even no where it goes.
Try it out yourself it is pretty interesting.
It gets wet
They move faster.Particles on the outside of the balloon are slower.The particles will move faster due to an increase in their kinetic energy.
It might start to rust.
they will attract
The pressure of the air inside it. The higher the balloon rises, the lower the outside air-pressure. With less pressure outside, the balloon expands because of the pressure of the air inside it. Eventually, the balloon bursts, and scientists recover the instruments when they fall to earth.
the air pressure outside of the balloon decreases.
The pressure inside the balloon will be higher because the balloon will try to get smaller and thus the balloon will ascent due to the low density of the helium inside the balloon.
the balloon will inflate

They leave them outside.
If you wait long enough, you eventually wind up with one warm balloon and one cold one.
The internal air would cool down and contract (lessen) the balloon's volume.
If perfume is sprayed inside a balloon and then the balloon is blown up, you can still smell the perfume from the outside of the balloon. This is because the material of the balloon is thin.
The pressure inside the balloon has to exceed the pressure outside the balloon.
As in balloon-powered rockets, a reduction in energy within the balloon can be accompanied by force exerted to move the balloon, or another object. The energy stored in a balloon is in the form of higher pressure stretching it out. If the balloon has an opening, the air will be forced out until the balloon regains its unstretched shape. At that point, air inside the balloon is at the same pressure as the air outside the balloon. Other containers can also store air at a pressure higher than the outside air. This can also provide force when the stored energy is released.
