It doesn't, it's just strong enough to counter it by the thrust generated by the expanding gasses.
It's a lot like the way your leg muscles defy gravity when you walk up some stairs.
A levitating ping pong ball defies gravity and floats in mid-air due to the Bernoulli principle, which states that an increase in the speed of a fluid (such as air) results in a decrease in pressure. When a ping pong ball is placed in a stream of air, the air moving around the ball creates a low-pressure area above it, causing the ball to be pushed upwards and levitate.
Helium defies gravity because it is lighter than the air around it. This causes it to rise upwards, creating a buoyant force that opposes gravity. This is why helium balloons float in the air.
Helium defies gravity because it is lighter than the surrounding air. This causes it to rise and float upwards, rather than being pulled down by gravity like heavier objects.
When you drop a ball, the action force on the ball is the force of gravity pulling the ball towards the ground.
Yes, gravity affects a soccer ball when it falls. The force of gravity causes the ball to accelerate towards the ground at a rate of 9.8 m/s^2. This acceleration causes the ball to pick up speed as it falls.

A bra that defies gravity.
The plural of defy is defies. As in "this defies the laws of gravity".

You cannot, it defies gravity

If you were observing the ball from the outside (of the ball) the center of gravity is in the middle of the basketball.

When you drop a ball, the action force on the ball is the force of gravity pulling the ball towards the ground.
When the ball is in the air, gravity brings the ball back down.
The virtual gravity bowling ball is one of the most highly reactive bowling ball in the world.
