What happens when a ball is filled with helium?
What happens when a ball is filled with helium?
What would happen if they were filled with helium? Filling it with helium would thus give rise to a buoyant force that can lift 0.03 g – much less than the actual mass of the ball, which is 2.7 g. Trying to make a soccer ball float by inflating it with helium would likewise fail.
Do professional soccer players use helium balls?
Soccer Balls Are Filled with Helium Apparently some people still believe this strange myth, but no, balls used in professional soccer matches are not filled with buoyant helium instead of oxygen.

How does air pressure affect bounce of a ball?
With more air in the ball, the air starts at higher pressure and pushes back that much harder when the ball is bounced. So that short answer is that more inflated basketballs bounce better because they have more air pressure inside them….
