to make an egg lout it takes at least five tablespoons of salt
It depends on what type of salt you use to make the egg float. it would be a fun science fair project for elementary to middle school. my son did this and he had a lot of fun. i used Walmart brand salt and it works best

∙ 13y agoAn object floats if the water it displaces weighs more than the object itself does.
Salt water is denser than fresh water. The more salt in the water, the more dense it is, and the more that the amount of water an object displaces will weigh. It is therefore possible that if you have some object in fresh water that is just a little heavier than the water it displaces, you could add salt to the fresh water until the object weighed less than an equivalent volume of the now salty water-- at which point the object would float to the surface.
How much salt it would take depends on the object. If the object already floats in fresh water, adding salt to the water will only make it float a little bit higher. On the other hand, many materials-- most rocks, iron, and so on- are denser than pure salt, and wouldn't float in "salt water" even if you put so much salt in that there was no water left.
Incidentally, I once saw aluminum floating like a cork on melted lead. Even iron will float on molten lead, because the lead is so dense. It was a surprising illustration of how bouyancy works, and a very startling thing to see!

What is in the salt water why the egg float?
Salt water have a higher density.So it can produce enough upthrust to make the egg float.
How much salt does it take to make and object float?
It depends on the density of the water and the weight of the object.
