Spring is in the air, and that means it’s time to break out the eggs, the food coloring, and—of course—a little science! If you’re looking for a fresh spin on egg dyeing this year, I’ve got just the thing: fizzy egg dyeing using baking soda, food coloring, and vinegar. Not only is this activity ridiculously fun (who doesn’t love a little fizz?), but it’s also a great way to sneak some STEM learning into your day.
