What else can I help you with?
A smooth piece of aluminum foil can be seen in your reflection but why not the crumpled piece?
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.
Why might a tightly crumpled ball of foil sink but a flat piece of foil of the same mass float in water?
The tightly crumpled ball of foil has a smaller volume with less air trapped inside, making it denser and likely to sink. The flat piece of foil has a larger surface area and traps more air, increasing its buoyancy and allowing it to float despite being the same mass as the crumpled ball.
Why does the same piece of foil float or sink?
The same piece of foil can float or sink depending on its shape and how it is positioned in the water. If the foil is shaped to trap air, it will float. If the foil is crumpled or folded so it doesn't trap air, it will sink.
What happens when light hits foil?
When light hits foil, it reflects off the surface of the foil due to its smooth and shiny nature. The reflective property of the foil causes the light to bounce off in various directions, creating a glare or shine. If the foil is crumpled or wrinkled, the light will scatter in multiple directions, creating a diffuse reflection rather than a focused shine.
What can you use to replace the jiggly thing on your pressure cooker?
crumpled-up aluminum foil
Why do you look funny when you look at your reflection in aluminium foil.?
Because the aluminum foil is not flat or in one plane or "straight". When it reflects light, which is a part of your reflection, the reflected light does not come back straight, but gets sent in different directions. For example, the light from your lips might get reflected at an angle, and your eyes will see that "lips-light" where it is expecting light from your teeth. Thus, you will look funny because you will see your teeth where you were expecting your lips in the mirror. Many other parts of your face might get distorted or not appear where they should be, either just slightly away or moved quite a bit. This can created a stretched view in some areas of the face and a compacted view in another, leading to the funny reflection.
Which weighs more a sheet of aluminum foil or the same sheet crumpled into a tight wad?
I see no reason why the weight should change if you crumple it.
What type of luster would a piece of aluminum foil have?
A piece of aluminum foil typically exhibits a metallic luster. This shiny, reflective surface is characteristic of metals, allowing it to reflect light effectively. The smooth texture of the foil enhances its luster, making it appear bright and silvery.
Does a crumpled piece of aluminum foil into a ball would the mass weight volume and density increase or decrease from what it was?
Crumpling aluminum foil into a ball would not change the mass of the foil, as the amount of material remains the same. However, the volume would decrease as the foil is compressed into a smaller shape, leading to a higher density due to the same mass being packed into a smaller space. The weight of the foil would remain the same regardless of its shape.
Does foil catch light or prevent light?
Foil reflects light

What are physical properties of a piece of aluminum foil?
