What’s happening to my gummies?
Acetic acid in vinegar plus bicarbonate in baking soda equals carbon dioxide gas bubbles. Acid + Base = Bubbly reaction. The baking soda absorbing into the gummy worms makes bubbles when transferred to the vinegar. Bubbles rise to the top, taking your gummy worm with them giving the appearance of wiggly worms.
Try different gummy worm lengths and sizes to see which ones wiggle the most, which ones wiggles the least, and which ones don’t wiggle at all. Take notes in a notebook and draw some pictures. Measure with a ruler for exact measurements.
What other gummies wiggle? Gummy bears, gummy spiders, gummy insects?
