Generally speaking, a denser substance will sink in a less dense substance. Assuming standard temperatures, since aluminum has a density of about 2.7 grams per cubic centimeter and water only has 1 gram per cc, aluminum would sink. A thin aluminum foil could float by virtue of the surface tension on water (but if submerged, will sink). An aluminum boat would float because it displaces a greater mass of water than its own weight. An aluminum block could also float on a liquid of higher density than the aluminum.
A tin foil raft, which is just a flat piece of tin foil (which we know is really aluminum foil), floats by means of the surface tension of the water that supports it. We all know that aluminum is more dense than water. A block or other chunk of aluminum would sink in water. But because the aluminum foil is thin, its mass is "spread out" over a wide area, and this causes a broad interaction with the surface tension characteristic of water.

Salt water is more buoyant than fresh water is, because salt water is slightly more dense. -- Anything that floats in salt water will float higher than it does in fresh water. -- Anything that sinks in salt water will sink slower than it does in fresh water. -- Anything that just barely floats in salt water may possibly sink in fresh water.
object that sink in water
yes metal sink in water
A tightly crumpled ball of foil might sink in water because it's density is greater than water. When foil is flat it's density is less than water and it will float.
A thin aluminum foil can float on water if placed carefully flat on the surface because of the surface tension of water. If you were to submerge it, the foil will sink.
They sink.
A Rock would obviously sink in water and a egg would float in salt water Believe it or not bowling balls that are denser than water float!
A thin aluminum foil, (which is denser than water) could float on the surface if carefully placed, by virtue of the surface tension of water. But if submerged, the foil would sink due to its higher density. Generally speaking, a denser substance will sink in a less dense substance. Assuming standard temperatures, since aluminum has a density of about 2.7 grams per cubic centimeter and water only has 1 gram per cc, aluminum would sink. (An aluminum boat would float because it displaces a greater mass of water than its own weight.)
A thin sheet of alu foil may stay on the surface as long as there is no water sprayed on it nor immersed under water, then it will sink.

you use a strong material like wood and then put the tin foil over it, so it is waterproof because if you did not put a waterproof material on it would absorb the water and sink.
The property that separates styrofoam balls is their buoyancy. Styrofoam balls are lightweight and have air trapped inside, making them less dense than water. This causes them to float on the surface of water, separating them from denser materials that sink.
The aluminum foil is less dense than the water which makesit float. Aluminum foil is not less dense than water. It is more dense. The reason that aluminum foil floats is that the surface tension of the water will hold the sheet of foil. If you still think that the aluminum foil is less dense than water, try floating a roll of foil in a bucket.
