About this coloring page
One drop hangs in mid-air between the dropper and the flask below, frozen at the exact moment before the fizz begins. Inside, bubbles of every size crowd the cone-shaped glass, and two have already floated free of the neck. Kids who've done the vinegar-and-baking-soda trick at home will recognize the situation immediately.
Bubbles are the fun part. Color the liquid one bold shade and leave every bubble white so it pops, or treat the circles like a bag of gumballs with a different color apiece. Line weight stays thick and forgiving throughout, which makes this an easy pick for younger scientists. For a rainy-day pairing, print two free copies and let siblings race to finish.
