I dont know sorry
so that the solution would not evaporate
Take a makeup mirror, and look at yourself in the mirror. Then, rotate that mirror by about 10 degrees. What do you see happen to the image in the mirror? Now, take a ball of foil and examine its surface closely. The light reflects off each small area in a different direction. As with a mirror, the light rays are reflected back in parallel from the polished side of aluminum foil. But when it is crumpled, the rays reflect in many directions from the angular facets.
Physical. It's still aluminum foil.
an element. its made entirely out of aluminum
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.
You wrap the piece of bread in a piece of foil. You can also leave a mirror a few feet away if the reflection is on the foil! I'm not sure how long that would take though!
Yes you can. You can leave a piece of bread in foil in the sun. You can all so leave a mirror a few feet away from the bread. The mirror has to have a reflection of the sun though.
ummm...Yeah....With foil
because it is folded
I would have to say aluminum foil, since radiation can travel through glass. radiation is reflected from the surface of aluminum foil. With a mirror the radiation has to travel through a small layer of glass twice before the mirror is finished with it. Glass is not totally transparent, some light is absorbed so the naked aluminum reflects better.
a mirror will be the best one to use

A mirror, or the shiny side of tin foil
The aluminum foil is smoother.
A piece of aluminum foil has a fixed mass and volume, it is flexible, and it is a metal that can conduct electricity.
Block foil printing is producing gold (silver) foil printing on a piece of wood.
