No you can not make aluminum foil change colours. Because it is already galvanised all chemical colour changing will not work because the aluminum is coated.
You can make your own simple Solar Eclipse Viewer with a couple of cardboard boxes and a piece of aluminum foil, and a pin.
No, not necessarily.
Beating aluminum to make aluminum foil is a physicalchange, and not a chemical one. Note, however, that aluminum is generally rolled to make foil rather than beaten. The ductility of aluminum is a physical characteristic of this amazing metal that makes it possible for us to do that.
depends on foil:aluminumgold (usually called leaf not foil, most common use is lettering on leather bound books)silver (usually called leaf not foil, most common use is lettering on leather bound books)tin (used for purpose aluminum foil is used for, rarely seen today)lead (often used in roofing to prevent leaks from pooling water, thick for foil)etc.
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.
Yes. If you keep e.g. your cheese piece wrapped in aluminum foil, given enough time, it will dissolve the aluminum and give it many irregular holes. The dissolved aluminum will appear on your cheese as irregular metallic coating, sticking firmly to the cheese.
You can make guitars out of aluminum foil in any way that you'd like. You can for example cut out a guitar shape in the foil and drawstrings on it with a marker.
Answer #1: float.==========================Answer #2:The density of aluminum is 2.7 gm/cm3.So, just like steel, if you shape a piece of it just right so that it displacesenough water, you can make it float. But a lump of it will sink in water.
Aluminum foil is not an element as the foil has a small amount of other stuff added to it to make it an alloy. Aluminum element would only have aluminum atoms and no other compounds added to it. An alloy has two or more metals together.
yes that is how the make them.

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.
Aluminum foil is thin and brittle. It might be OK for a small toy, but that's about it.
