the way to make a penny float is the same way as making an egg float.All you have to do is add salt alot until you see the penny float and that's about it

it will float bc the penny is so light that it should float.

An egg will float in anything with a density greater than an egg.

no. a penny can not float on water. only a feather can do that, i think. sorry!

Yes, if it makes the water denser, the boat will float easier. For example, it is easier to float in salty water.

A penny will not float in water, mainly because it is denser than water. When the penny is placed in water, it displaces a volume of water equal to its own volume. Since the penny weighs more than the water it displaces, it will sink.So, in order for the penny to float, you must find a liquid that is denser than solid copper -- or whatever metal or alloy a penny is made of. Mercury -- which is a liquid at room temperature -- is denser than copper. Hence, a penny will float in mercury.Possibly surface tension may allow it to float.

The surface of the opocorn or raisin allows bubbles to form and they stick to the surface. This allows them to float.

Water can float on vinegar. That is because vinegar's substances are different.

Many combustible substances (substances that will burn) are lighter (less dense) than water and will float - paper, wood and gasoline are a few examples. When ignited (set on fire), these substances will continue to float, and so will the fire.

Because a basketball is full of air and a penny isn't

Substances that float float better in salt water then in fresh water because salt water is more dense as a result of the salt that is dissolves in the water.

A penny as everyone I'm sure knows cannot float in regular water. As for salt water a penny should in theory not be able to becase the regular pennys bouancy is not great enough to support the weight of the penny regardless of the salt to water ratio. A penny is too dense to be able to float in salt water, regardless of the salinity of the solution.

pennies dont float in water I have heard that it is possible to float a penny, due to surface tension, but I have never seen it done, nor have I been able to do it. I have floated razor blades, though.

It is waters greater density than air that allows some substances to float on water.

more dense substances sink, less dense substances float. oil will not sink in water, it will float, it is less dense.

Substances with a density (mass per unit volume) greaterthan a liquid will sink in the liquid; if the object has a lower density it will float.

it take about 900milligrams of salt

it would depend on the density of the liquid and the penny. if the penny is lighter then the liquid in density, then it will float. if it is heaver in density then it will sink <><><><><> One example might be mercury. At a density of 13.5 g cm-3 it would float a copper penny which is only 8.9 g cm-3. HOWEVER: DO NOT TRY THIS, because mercury is a significant poison, and can be directly absorbed into the skin.

a penny sinks in water because the penny is denser than water,so even if the penny is on the moon,its density is still larger than water,and the penny would still sink.

Wood and styrofoam, to name two.

when the penny is reacted with HCl, there must be somesort of area where the copper on the outside of the penny is removed so that the HCl can react with the zinc inside because HCl does not react with copper. Once the HCl reacts with the Zn inside, it will dissapear and therefore become less dense then the ZnCl2 that is formed which causes the penny to float

I suspect that "flow" is meant to also be "float", but even with that substitution, it just changes the question from nonsensical to counterfactual.Most things that float in water do not float in air.

How can you make a chocolate float or sink
