This is a common way of checking duck and chicken eggs for freshness. If the egg stays at the bottom of the jar, it is very fresh. If if suspends towards the middle, it is not as fresh, but it is still edible. If it rises almost to the top or floats, the egg has likely gone bad. It has to do with the air pocket inside of the shell expanding as the egg ages.
If water contracted on freezing, it would have catastrophic implications for aquatic life. Instead of the ice staying on top at the surface of the water, it would sink if it contracted. This would kill aquatic life.
Sadly no. If they fall in water they will sink to the bottom and go kapput.
An ant doesn't sink in water because it is able to repel water due to the hydrophobic nature of its exoskeleton. The fine hairs on an ant's body trap air bubbles, giving it buoyancy and allowing it to float on the water's surface.
my son found duck eggs in a wheat field they were burning. the hen was sitting, but he got them so they would have a chance to survive. I put in an incubator but some of the eggs are dark under the shell are these good eggs?
A dense heavy bone would not float and a skull without any internal contents through decomposition or insect infestation would not hold water or a probable air pocket and so would sink, light porous bone might float especially in sea water. If a skull had previously been buried and there had been a gradual filling of the cranial cavity with soil so that an air pocket was formed within the area above the ear holes and nasal hole, a skull might float, at least until the soil dissolved.

A paper clip is denser than water, so it would sink if placed in water.
It would sink. The density of water is 1g/mL. Anything with a greater density will sink.
Gold is a very dense metal, so it would sink in water rather than float.
If the refrigerator water is filtered, then it would be different from the tap water coming from the sink.
The sand puts weight on it and it makes in sink.
Iron fillings are denser than water, so they would sink when placed in water. Since water has a lower density than iron fillings, the fillings will displace the water and sink to the bottom.
a solid ceramic object would sink. however, if the object is displacing enough water proportional to it's weight, then it will float. If you put an empty glass bowl in the water, it will float; but if you allow water in, it will sink. This applies to ceramics.
Sometimes it will back up from a dishwasher (machine)
A magnet would typically sink in water as it is denser than water and does not have the buoyancy to float.
Sink in what water? Well, not taking in account that the electric wires in the toaster shouldn't be immersed in water, a toaster would sink because its density is greater that of water. Had it been less the toaster would float.
