It’s Valentines week – love is in the air and there is candy flowing everywhere. What are you going to do with all of the candy your child brings home on Thursday afternoon? Don’t eat it…experiment with it.
Here are a few experiments shown in the video -
The Ups and Downs of a Relationship – Candy Heart Soda Dance
- Fill a clear glass with 7-Up, Sprite or other carbonated drink.
- Drop a handful of candy conversation hearts into the soda.
- Watch the hearts dance up and down in the carbonation.
The carbon dioxide picks them up and throws them to the top of the glass. When they reach the top, the bubbles burst and the candy works its way down again.
Skittles and M&M’s Letter Float
- Fill a clear glass or bowl half way with water.
- Drop a few M&M’s or Skittles into the water.
- Wait about 10-20 minutes to let the candy soak.
How Does This Work?
The “M” and “S” letters on M&M’s and Skittles are printed in edible white ink. The ink won’t dissolve in water. When the candy shell dissolves, the letters peel off and float to the top.

Pop Rocks Expander
- Pour an entire packet of Pop Rocks into a balloon.
- Stretch the mouth of the balloon over the opening of a bottle of soda. Carefully to avoid the Pop Rocks from spilling into the soda.
- When it’s secure, dump the balloon over and empty the Pop Rocks into the soda.
Gobstoppers or Skittles Color Mix
- Fill a petri dish with enough water to cover the bottom.
- Drop a Gobstopper of different color along each side so that they are across from each other and evenly spaced.
- Wait and observe.
Science-Based Inquiry Tests
Try this experiment with other dyed candies, like M&M’s Skittles, Lifesavers. Do they all work the same?
Try it with different liquids, like milk, vinegar or soda. Do the colors spread the same?
Now try putting two Gobstoppers in a petri dish, then three. What happens?
Finally, test different temperatures in the water. What happens to the dissolve rate in cold water or hot?
Gobstoppers have at least four layers of of colors, so your petri dish rainbow should change colors four times during this experiment.
The Gobstopper colors do not mix. They all run into eachother and stop.
