Check out this fun Halloween themed experiment on YouTube!
Materials: clear glasses, vinegar, baking soda, warm water and gummy
worms
The gummy worms float and move as the vinegar (acetic acid) in the cup reacts with the baking soda (sodium bicarbonate).
This chemical reaction forms carbon dioxide gas bubbles which float to the surface and wiggles the worms.
Observation questions:
What happens if you drop M&M’s in the solution?
What happens if you drop Skittles in the solution?
