The only possible reason for that would be that after the object floated for a while,
the salt ate a hole in it, the water poured into it, and it stopped floating.
If the object doesn't corrode, dissolve, or get water-logged, then it might float in
salty water and sink in fresh water, because salty water is always more dense
than either fresh or distilled water.
A perspex block sinks in fresh water because it is denser than the water. In salty water, the added salt increases the water's density, causing the perspex block to float. This is due to the principle of buoyancy, where an object will float if it is less dense than the fluid it is in.
Objects always have more buoyancy in denser fluids than less dense fluids. Therefore, swimmers would float more easily in very salty water.FUN FACT:The Dead Sea, in Jordan, Israel, is so salty that you can float on the surface!
Oh honey, pay attention. Objects float more easily in salt water because salt water is denser than fresh water. It's like trying to float in a kiddie pool versus a hot tub - one is gonna keep you afloat better than the other. So, if you wanna float like a boss, head to the beach and let that salty water do its thing.
The difference in density between the perspex block and the water is what determines whether it sinks or floats. In fresh water, the density of the perspex block is greater than that of the water, causing it to sink. However, in very salty water, the increased density of the water allows the less dense perspex block to float.
Only about 10 of the water that evaporates from a salty ocean is fresh water.

A fresh egg don't float in pure water; in a salty water the floating depends on the concentration of the salt in solution. The salty water is more dense.
Salt water is denser than fresh water. A ship will float higher on the oceans, and float lower on a fresh water inland lake.
Salt water is more dense than fresh water. A ship would float higher at sea, and lower on a fresh water inland lake.
Eggs float in salty water because the density of the salty water is higher than that of the egg, causing it to float. In ordinary water, the density of the egg is higher than that of the water, so it sinks. The increased density in the salty water creates more buoyant force, allowing the egg to float.
It is easier to float in salty water than in fresh water because the higher salt concentration in the water increases its density, making objects more buoyant. This buoyancy helps you float on the surface of the water more effortlessly compared to in less dense fresh water.
I think that salty ice cube do float in water because ice bergs float it water and they're made of salty water. i think i depends on the density (Amount of salt) in the ice
float
A Rock would obviously sink in water and a egg would float in salt water Believe it or not bowling balls that are denser than water float!
fresh :)
