In this demonstration a beaker of hot(red) water and a beaker of ice cold(blue) water are added to a tank of room temperature water. As seen, the hot water rises to the top of the tank, and the cold water sinks to the bottom.

  • Awesome, straight forward, empirical demonstration. Great job!

  • i agree with wolf. water is has three different state. Gas, Liquid, Solid, and everything in between. I read that Gas has a density of .0006 g/cm^3. Thats why we can move through it. Hey can any1 guess our density, since we can move through liquid state of H^2O and not Solid ICE? Swim Skate n' Fall

  • @wolfcryseether warm water has a lower density than the room temperature water, so for the archimedes' principle it floats on the surface. Cold water has a higher density, so it lays on the ground.

  • ...what makes the water to behave the way it did?? thanks very much

  • Science Rules!!

  • does anyone know how to float logs heavier than their own weight in water? I do I do

  • Whoa! You just blinded me with science!
