Added in 75.0, Gel can absorb {{MaterialBtn|WATR}}, in a similar manner as {{MaterialBtn|SPNG}}. While absorbing {{MaterialBtn|WATR}}, it becomes darker and less viscous and its heat conductivity increases. If in contact with {{MaterialBtn|SPNG}}, water passes from gel to sponge. When gel touches {{MaterialBtn|PSTE}} it will drain the water from it and the {{MaterialBtn|PSTE}} becomes {{MaterialBtn|CLST}}.  If a gas touches the surface, then it will be randomly pulled across it and deposited somewhere else, useful in liquid/gas separation. Also appears to "stick" to gases. Another interesting reaction occurs when gel touches a solid object. It will coat the solid, even when on the bottom of the object and/or the objects sides. This can make it difficult to remove manually. The "thickness" of the "stuck" gel is inversely related to the deviation from the gravitational "down".
