Best Answer: IMAX is a special kind of theater. Most of the time an IMAX theater is much larger than a standard movie theater. The seats lean back and you watch the movie on a giant screen on the ceiling. It is a really cool experience because it engulfs you and you feel like your actually there. Definitely a good experience.
Silica sand is one of the most common varieties of sand found in the world. It is used for a wide range of applications, and can be purchased from various suppliers throughout the world. Silica sand is used in industrial processing, to make glass, as fill, and to create molds and castings.
Silica gel is obtained by taking out water from a precipitate of silicic acid.The gel absorbs water (as well as some other substances) and is used to dry and remove the color from objects. 1  Large volumes of silicon occur naturally in silicate minerals and as silicon dioxide, the principal constituent of natural sand. The three most common current deliberate uses of silicon are as glass, in semiconductors, and in silicone polymers. Silica (sand) is the main ingredient of glass, and is also found in the human skeleton. Silica and silicates are also used in the manufacturing of cement, porcelain, glass, and glazes. Silicon, when doped with boron, gallium, phosphorus, or arsenic is used in transistors, integrated circuits, computer chips and solar cells because it is a good semiconductor.
