All you would have to do is change the density of the cork or the water. An easy to do this is to create air pockets in the water. This will make the water less dense and it wont be able to "sink" underneath the boat. In other words, the water/air mixture created by the bubbles, will be less dense than the boat. And everybody knows that the denser object sinks, so then the cork will sink. The cork will stay sunk as long as you are creating bubbles.

∙ 12y agoWhether an object floats in water or not depends on its density, or how many atoms are in a given volume. For example, the density of water is 1. An object with a density of 0.5 will float in water (as it has a lower density) and an object with a density of 2 will sink (as it has a higher density).

The density of alcohol is roughly 0.8. If there is an object with a density of 0.9, it will float in water but sink in alcohol, as 0.8<0.9<1.0

A cork piece floats on water but an iron nail sinks give reason?
Things that are less dense than the water they displace will float (like cork) Things that are more dense than the water (like a nail) sink.
Are corks lighter then marbles?
Yes, a cork will often float on the surface of water, depending on the cork's density. But a marble will sink in water because of its weight. It will not float on the surface.
Explain why steel sinks and cork floats?
A substance that has more density than the liquid will sink. With less density, it will float.
Why does a niddle sink in water?
A metal needle will sink in water, because it weighs more than the water does, and since it is not buoyant, it sinks.
How can an ice cube float in a glass of water?
ice cube floats in water because it is dense and heavy if u compare water to alcohol then an ice cube will sink in the alcohol because alcohol is less dense which means its light.
Does cork float or sink in water?
it floats
Can you make water light enough to sink a cork?
no
Why does a wooden cork float in water but an iron nail sink?
Wooden cork is less dense than the water and the iron is not.
Why do object flout or sink?
If it is heaver than water (or what ever liquid you put it in) it will sink. Lead will sink. A cork will float.

Is an objects density determines whether it floats or sinks in water?
yes it does. try to sink a cork. it doesn't sink but on the other hand a iron nail does.the higher the mass the more the density and so the object sinks.
If a magnet is left to float freely on a cork in which direction will it end up pointing?
no the cork will sink
Is cork float or sink in water?
If you dropped a cork in a container of water, the cork will most definitely float. As to the cork is lite, like a feather and it doesnt container much mass.
A cork is able to float on water because it is?
A cork is able to float on water because it is less dense than the water. The reason why is because an object with more dense then itself it will float and an object with less density will sink in the fluid. HOWEVER if the object (such as the cork) has the same density, the object will neither float nor sink; instead it will stay at the same level in the fluid. So TECHNICALLY it is considered floating. So corks count as floating because it has less dense than the water. Sources: (Science: Glenco textbook)
Does a glass float or sink in water?
It depends on the shape of the fork and the material from which it is made. Most non-metal (wood, plastic) forks will float. Metal forks will sink unless they are shaped to have a large enough surface area on the bottom.
Why an iron nail sinks in water whereas a cork for the same size floats?
Correct me if I'm wrong, but i believe that cork floats on water because its cells are empty.Any object dropped into a liquid displaces that liquid. A floating object weighs the same as the liquid it displaces. An object that sinks, weighs more than the liquid it displaces, so the stone is heavier than the cork causing it to sink. and not just that, cork is a lot less dense than a stone is.
