Suppose you have a rubber ball 1 foot in diameter, and a latex balloon filled with helium until it is 6 inches in diameter.

Which has a greater buoyancy force?

The rubber ball.

The formula for buoyancy:Buoyancy Force = Fluid Density * Object Volume * Gravity
As you can see, buoyancy force has nothing to do with the density of an object, just the volume, so since the ball takes up more space then the balloon, it has a greater buoyancy force.

In Mrs. Sharma's Science class, they are holding a contest. She has a glass bottle, and a little bronze ball, the size of which is the exact same as the hole in the bottle. Mrs. Sharma is giving the student who can put the ball in the bottle, without breaking the glass or destroying the ball somehow and get an iPOD.

In her room there is a microwave, petroleum jelly, a stove, and a freezer.

Six of her seven students attempted this feat, but with no luck.

After the sixth student, the seventh, Gagan, comes up to the bottle and the ball. He thinks of using one of the tools in Mrs. Sharma's room at his disposal, and uses one (not the jelly as it was already proven to not work) and five hours later, gets the ball in the bottle and his free iPOD.
