This experiment made my mother nervous. It was short but I learned something I never knew about. I had four identical glasses and filled two with cold (blue water and the other two with warm (yellow) water.
I started off by picking up one of the warm water bottles and place an old playing card on top. I inverted it and attempted to place the warm water on top of the cold one.
I had to carefully put the bottle on top and align the tops of the bottles to each other. Then I carefully removed the card.
There was some spilling but it was a success. Look at this!
The water is staying separate! WHY?? We will get to that later. With the other two bottles I did the opposite. I put the cold bottle on top of the warm bottle and the first time I made a mess!
I cleaned up and reset! The second time I succeeded!!
The colors are mixing!! Why is it mixing this time? Well hot water is lighter than cold water. So when the warm water was on top it stayed there because it was lighter. In the second one, the cold water was on top so since it was heavier than the warm water it switched places and the colors mixed! Cool! I never knew that warm water was lighter than cold water.
The WOW-rating for this one is a 4. A little under let’s do it again. This one was fun in a colorful way!
