Sandboxes are boxes that tend to contain sand in them. They are typically used as entertainment, though they can also be used industrially and experimentally for such applications as softening an object or person's descent or to demonstrate or experiment with physics regarding the sand inside. Such sandboxes are typically given modifications or are specially made for the activity in question. An example of such a modification would be the addition of pipes with small (roughly 1 mm) holes equidistantly punctured into them to the bottom of the box that allow compressed air flow into the box, creating a fluidized bed.
