EXPERIMENT
Fill a petri dish with enough water to cover the bottom.
Drop a Gobstopper of a different color along the edge of the petri dish. We would tell you to put them all in the corners, but the dish is round and doesn’t have corners. So you need to place the Gobstoppers at equal distances from from each other.
Now watch the colors!
HOW DOES IT WORK?
The surprise here is that the Gobstopper colors don’t actually mix in the petri dish. Instead, they run into each other and stop. In addition to the non- mixing colors, you’ll notice that the colors change during the dissolving process. This is because each Gobstopper is comprised of four different colors.
