What is your hypothesis?

One of the indulgences that is keeping us going now that I work is delivered groceries.  The frozen stuff comes packed in dry ice gets turned into a fun family activity practically every time.  This week Isabelle kept insisting we add food coloring.  Finally Jake says, "why what is your hypothesis?"  Without missing a beat Isabelle responds, "My hypothesis is that if we add food coloring to the water when we add the dry ice the smoke will be a different color."

So now we had to do the experiment.

We used blue and while the water looked great the smoke was still white.

Holding up the dry ice.

If you hold your hand over the smoke and then quickly pull up it follows you.

We added a little dish soap and it quickly bubbled up.  The smoke is inside every bubble making them fun to pop.

Just another fun filled evening at the Hardackers.
