- Cube is a Canadian science fiction/horror film series. The three movies are each based on the same premise; there is a gigantic, mechanical, cube-shaped structure (the purpose and origin of which is almost completely unknown) that is made up of lots of smaller cube-shaped rooms. Each of these rooms has 6 doors, one on each wall and one on the ceiling and one on the floor, which lead into adjacent, identical rooms, only differing by color. Some of these rooms are safe, while others are equipped with booby traps such as flamethrowers and razorwire which kill a person who enters the room (in some cases it is possible to detect a trap by throwing a boot into the room first, except in Cube 2: Hypercube where the traps are less distinct - in the form of an abstract shape and visual effects - and less predictable).
- Helium (Wikipedia)
Helium (from Greek: ἥλιος, romanized: helios, lit. ‘sun’) is a chemical element; it has symbol He and atomic number 2. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table. Its boiling point is the lowest among all the elements, and it does not have a melting point at standard pressures. It is the second-lightest and second most abundant element in the observable universe, after hydrogen. It is present at about 24% of the total elemental mass, which is more than 12 times the mass of all the heavier elements combined. Its abundance is similar to this in both the Sun and Jupiter, because of the very high nuclear binding energy (per nucleon) of helium-4, with respect to the next three elements after helium. This helium-4 binding energy also accounts for why it is a product of both nuclear fusion and radioactive decay. The most common isotope of helium in the universe is helium-4, the vast majority of which was formed during the Big Bang. Large amounts of new helium are created by nuclear fusion of hydrogen in stars.
