The viral "Stanley" tumblers and other high-end water bottles use a "double-wall vacuum" to keep drinks cold. This works because a vacuum contains no matter, meaning this type of heat transfer (which requires particles to bump into each other) cannot happen.

If you have a pencil and a diamond ring, you are holding two different forms of the exact same element. This phenomenon, where an element can exist in different physical forms, is known as an allotrope. Name the element.
