Leaves are shiny on the top side due to the presence of a waxy cuticle that helps to prevent water loss and protect the leaf from pests and pathogens. The bottom side of the leaf is usually duller to allow for more efficient gas exchange with the surrounding environment through tiny pores called stomata.
When printing pictures, the shiny side is usually the top side because it typically has a coating that enhances image quality and color vibrancy. The dull side is typically the bottom side where the ink is absorbed.
The shiny side of aluminum foil should be facing outwards for better heat reflection.
The shiny side of aluminum foil reflects heat better than the dull side.
When cooking with foil, use the shiny side facing out to reflect heat and the dull side facing in to absorb heat.
Aluminum foil is shiny on one side because of the manufacturing process. During manufacturing, the foil is rolled to make it thinner, which creates a shiny side. The dull side is created by the contact between the foil and the rolling machinery.

the right side
If you are baking something wrapped in foil, you should probably have the dull side of the foil out. The dull side reflects heat a bit less than the shiny side. This means that cooking with the shiny side out would make your food cook more slowly.
The shiny side of aluminum foil should be facing outwards for better heat reflection.
It is a result of the rolling process, manufacturers roll a large ingot of aluminum through successivly smaller thickness of roller so the ingot gets thinner and thiner, however for the very last roll the aluminum is to thin to be rolled alone, so they put through two sheets, the sides which face each other become dull.
You should use tin foil with the shiny side facing inwards towards the food and the dull side facing outwards when cooking with fire. This can help reflect heat away from the food and prevent the foil from burning.
The "inside" of tin foil is the dull side. The "outside" of tin foil is the shiny side.
The shiny side of aluminum foil reflects heat better than the dull side.
When cooking with foil, use the shiny side facing out to reflect heat and the dull side facing in to absorb heat.
The DVD is played from the shiny side. This means that the shiny side of the DVD, is what faces the bottom of the DVD player or drive. A laser reads it, and this is how your DVD works

Shiny side up. The reflective surface is designed that way to deflect radiation better. But, babies won't die if you do it the other way around.AnswerTake it from the people at Reynolds. They make the stuff. They will tell you that it makes no difference which side is in or out. Optical light scatters differently from the dull side than from the shiny side, which is more like a mirror. But both sides absorb or reflect light (and infrared radiation) equally. AnswerScientifically speaking, the shiny side is better top be towards your food when cooking--the reflective surface makes for slightly faster cooking. The dull side should be towards the food when freezing--the shiny side outwards will keep any heat that would enter at bay better.These make very small differences, however, and your food will probably come out APPROXIMATELY the same either way.
