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
if u made the piece ofmetal hollow it can float unless its density is larger than the water densityANSWER:If you make it displace more water than what makes it sink, it will float, as in a ships hull. If you make pontoons out of it, it will float. If you make an enclosed shape that contains enough air, it will float. There should be less density in the item than the water.
no cobalt does not float on water, it has no way for air to seap through, there fore, it cant float
That depends what object you want to float.
Put it on a boat?
it will float bc the penny is so light that it should float.
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.
penny's aren't tall enough!
because you're fat
no it wuld float on surface......
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
All pure metal sinks, only by entrapping air in waterproof compartments can you make it (ships) float.
How can you make a chocolate float or sink
what make stuff sink or and float
Only special bought golf balls float, and they are designed with air inside. That air obviously is lighter than water and will always rise, a penny however has no air and is stream lined to slide through the water. :D
You can't make things float, things float by it's self's it's density is lower than 1 it can float, if it's density is greater than 1 it can't float.
