Silicon oxide on the moon

    It is said that the tides on earth are due to the moon's gravity. But the moon consists half of silicon oxide, the stuff that also comes with the new camera/shoes in that little bag, and acts like a moist absorber. So maybe there are two reasons for the tides?

    And if ocean water feels the attraction so much of the moon, how about other stuff on earth than water?

    Silicon oxide absorbs moisture by direct contact. The moon and the ocean are a little too far apart.

    And yes, all materials are affected by tidal forces.

    Was that a real question?

    SiO2 is essentially sand and is not a dessicant. Silica jel is a dessicant made from SiO2. Silica jel usually comes in the form of beads that have a large porosity, it is this porosity that is responsible for it's use as a dessicant. Don't know if this was just a joke, but as you can see there is a big difference between sand or glass and silica jel.

    Correct. They use it widely because if a child accidentally ingests some, it is no different than eating sand.

    A better dessicant is CaCl2 (cackle two), which adheres the H2O to the molecule directly. In SiO2, the high porosity allows for trapping. Cackle-two is a powder naturally, allowing for ease of attachment of the H2O in light bonding (not covalent or ionic, but polarization of the molecules allowing for attraction of opposite poles).

    I have quite a decent chemistry background, but from some time ago.

    Is Cackle-2 something that anyone else has ever heard of, or just another artifact of the stupidization of science so politicians and lawyers can argue with Creationists and cost time and money for no purpose?
