Why needle with grease float on water surface?
The needle with grease floats on water because the grease creates a waterproof barrier around the needle. When placed on water, the surface tension of the water is able to support the needle and grease due to the decreased contact between the needle and water. This phenomenon is known as the "floating needle trick."
Why does needle sink when placed vertically in water but does not when placed horizontally?
When a needle is placed vertically in water, the force of gravity acting on the denser needle overcomes the buoyant force pushing it up, causing it to sink. However, when placed horizontally, the buoyant force acting on the needle is greater than its weight, allowing it to float due to surface tension and the needle's low surface area in contact with the water.

How do you get a broken air pump needle out of a basketball?
We used chewed up, almost dried bubble gum to get it out when it happened to us. Good Luck!

If the needle has fallen through and is rattling around inside, you'll wreck the ball trying to get it out. Play on--it won't hurt a thing.
