Heat. Decreased pressure.
Or something that will increase the surface area.....
....something that will increase the surface area Air bubbling through it...... A giant sponge.......a pile of sand a pile of rocks..... More like you would be adding the water TO the substance.....
If your water is in a cone...adding anything that raises the water level will increase evaporation....larger surface area....
Lots of options for your vague question....
thank you for your response do you think dirt would result in the same results as sand
sand is better.
dirt consists of lots of organic matter which tends to trap the water into tiny pools
in good sand the water spreads homogeneously through it and maximizes the surface area of the exposed water
(I work at a horse rescue. This winter we're all too familiar with the drainage (and lack thereof) of even mildly polluted sand)
Probably....dirt is just really really fine sand.......the dirt particles would have to increase the surface area of the water exposed to air.....Like before....it would be more like adding water TO dirt rather than adding dirt TO water....
