Fill a plastic bottle with three-quarters coarse sand. Add water to saturate the sand with water. Let a little water float on top. On squeezing the bottle more water should pour out. Instead, the extra water is sucked in. Squeezing crushes the sand structure created internal cavities which suck the extra water!
