Which one sinks lemon or limes?

Here's why:

* Density: Lemons and limes are denser than water. This means they have more mass packed into the same amount of space.

* Buoyancy: Objects that are denser than water sink because the upward force of buoyancy (the force that pushes things upward in water) is not strong enough to overcome the force of gravity pulling them down.

Fun fact: You can make a lemon or lime float by dissolving a lot of salt in the water. This increases the density of the water, making the lemon or lime less dense by comparison!
