Yes, one example will be: add salt to the water.
Common metal earring don't float in water. However, you could design on that float by make it hollow. Jewellery design is unlimited, long as it can hung beautifully then anything could be possible, even using plastic to make an earring. I would think the back of the earring could be light and flat enough to be supported by the surface tention of water.
you can add salt to water to make the egg float because of it's density
add vinigar to the water
anything you want that can float. You can be creative.
No, salt, sugar, and flour alone will not make an egg float. The density of an egg is higher than that of salt, sugar, and flour, so the egg will sink in these substances. However, if you were to dissolve a large amount of salt or sugar in water to create a solution with a higher density than the egg, then the egg could float in that solution.
Yes, adding salt to water increases its density, which can make some objects that would normally sink, like eggs, float. By altering the density of the water, the buoyant force exerted on the object can be increased to make it float.
A rock could float if its density is less than that of water, as is the rock pumice, or if it is shaped in a manner that would displace an amount of water to sufficiently cause it to float when carefully placed in water.
Water has a higher density than air. Anything that is less dense will float. The tube's covering is not enough to make it sink when filled with air. That is also the reason that oil and water don't mix.
you put it in a cup of water or something that has water in it
The salted water is denser than pure water and eggs can float.
An egg will float in anything with a density greater than an egg.
it depends on how much salt is in the water. if there is enough, the soda can will float.
