Modeling Mantle Convection Currents

On the first of February, 6b had to do a lab. One of the reasons was because we had a test coming up and also because it included what we were kind of studying about. The materials we were meant to use were:  large plastic bottle, food coloring, small glass jar, aluminum foil, small pieces of paper, cold and hot water. We were focusing on observing for this lab. What we did was fill the plastic bottle with cold water, and the small glass jar with warm. Place the aluminum over the small jar and make sure it didn't go off. Finally, place the jar into the bottle and place some pieces of paper on the water, then we were meant to poke holes into the aluminum, and see what happened to the waters meeting and to the pieces of paper.
Hypothesis:
Before we even started the lab, my hypothesis was that when we punch the holes into the warm water, it will come shooting up and make bubbles, but I was wrong.(I was thinking of a volcano most probably)
Observing:
When my partner and I punched the whole into the colored, hot water, the color slowly started to get out of the jar and as it reached the top were the paper were, it started making some join and others disperse. The water was also moving anti-clock-wise and was not still. As I said before, my hypothesis was not right because nothing shoot up really fast, well except when I poked the holes in 2 or 3 bubbles popped up but no explosion or anything happened.
Conclusion:
As I mentioned in my observation,  my prediction was wrong because nothing came splashing out of the bottle except for the small bubbles that came running up when I poked the holes in. Also, in conclusion I saw that the warm water was actually pretty slow at rising, but it did rise, it was very similar to wind, the hot goes to the top and the cold to the bottom.
