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?
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.
Does a crumpled piece of aluminum foil into a ball would the mass weight volume and density increase or decrease from what it was?
All that has changed is the shape.
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.

Why wont water displacemant work well for finding the aluminium foil's volume?
Aluminum foil as a flat sheet doesn't fit well into the graduated cylinder, and if crumpled up, it may trap air pockets, and give an inaccurate result.
