Soccer balls do not contain helium. if they did, they would float like a balloon!
Actually, that's not true. A soccer ball would NOT float like a balloon--they weigh too much. It would, however, increase the distance ever so slightly over that of a regular air filled soccer ball. Eventually over time, the helium would dissipate, much like a helium balloon that slowly falls to the ground.

No, soccer balls are filled with ordinary air If they were filled with helium, they would float into the skyHelium filled soccer balls would certainly not "fly into the sky"! The difference in mass of an air filled ball and one filled with helium would be but a few grams! But the helium (having a much smaller molecule than those that comprise air) would leak out of the bladder more quickly. In addition Helium is much more expensive than compressed air.
No, Soccer balls contain oxygen and carbon dioxide. If they contained helium they would most likely float away.
