According to Archimedes' principle, the buoyant force is equal to the weight of the displaced fluid. Thus anything that weighs more than the fluid it displaces will have a net downward force, and will sink. Another way to put this, is that anything with a greater density than the fluid will sink in that fluid.
For example, in water, anything that has a mass of more than 1 kilogram per liter of volume will sink. Rocks have a density of 2-3 kilograms per liter, so they will sink in water.
In air, anything with a density of more than 0.00123 kilograms per liter will sink. A typical hot air balloon weighs about 3 tons (including the hot air), and has a volume of 3 million liters, so it weighs 0.0010 kilograms per liter, ans thus will not sink in air.

Why do heavy things sink?
Not all heavy things sink. Things that are more dense than the liquid around them will sink.
Why do things float or sink?
Air resistance.

What are some things that can float and sink?
ice
Do heavy things sink faster than lighter things?
In general, heavier things will sink faster than lighter things in a fluid like water due to greater gravitational force. However, factors like shape, size, and density can also affect the rate at which objects sink.
Why do some things sink fast and some things sink slowly?
The sinking speed of an object depends on its density and shape. Objects with high density and streamlined shape tend to sink faster, while objects with lower density and irregular shape can sink more slowly. The surrounding fluid's properties, such as viscosity and temperature, can also affect how fast something sinks.
Why do some things flaot while others sink?
Some things float or sink based on their density. Objects that are less dense than the liquid they are placed in will float, while those that are more dense will sink. Additionally, the shape and size of an object can also affect whether it floats or sinks.
Why some things float and other things sink?
Because of the objects density.
Do the most dense things float or sink?
The density of an object determines if it sinks or floats. If an object is more dense than the medium it is in, it will sink. If it is less dense, it will float. Therefore, the most dense things typically sink.
What are things that should not be thrown in sink in the lab?
