Tensile being poured and in water.

Tensile is a tan, globular material that sticks to itself in such a way that it forms globs or drops, like water with high surface tension. It doesn't boil, melt, burn, or put out fires. It will either float or sink in water, depending on the amount you drop on it and the height you drop it from. It is often used in Levels as the user element, and can make some interesting substances.
