Will this hurt if vinegar gets on skin or eyes?

If vinegar gets on skin it can sting if it is very sensitive, but it rinses off with water and mild soap. Keep a bowl of clean water and paper towels nearby. If vinegar gets into a child’s eyes, flush with water and seek help if irritation continues. I say this from doing similar kitchen experiments with curious kids many times; quick rinsing usually fixes it.

What age is right for this?

I trust this for preschoolers and up with close supervision. Little ones love the colors, but they also taste things. Watch them and guide the drops. If a child still puts items in their mouth, do not let them handle the vinegar or baking soda directly. Older kids, around first grade and up, can do most steps with light supervision and a clear first demo.

Can I skip baking soda or use something else?

The fizz comes from the meeting of an acid and a base. Without baking soda you will not get the same bubbly reaction. I do not recommend substitutes unless you know their chemistry. If you want less fizz, use smaller amounts of baking soda. If fizz overwhelms, reduce the vinegar pour instead.

How messy is this and how will I clean it up?

Expect sticky colored sugar on the tray and bubbly vinegar puddles. Wipe the tray with a damp cloth and wash bowls in warm soapy water. Most staining from food color comes out if you clean it quickly. If a child spills sugar on the floor, sweep or vacuum before it dissolves, and then wipe with a damp cloth.

Why did one color fizz more than another?

That usually happens because of small differences in how much baking soda you put on each mound or how much vinegar you poured. The texture and dryness of the sugar also change how the baking soda mixes. I have learned to make even pinches and steady drips to keep reactions balanced. It is a helpful chance to show kids how tiny changes make big results.

Instructions

Set up a tray on your table and protect the surface with paper or a towel. Arrange the small bowls so each color sits close to the center.
Put about a tablespoon of sugar in each bowl. Add two to three drops of food coloring to each bowl and mix until evenly colored.
Spoon each colored sugar pile onto the tray in small mounds, leaving space between piles.
Sprinkle a small pinch of baking soda on top of each colored sugar mound.
Fill a dropper or small cup with white vinegar. Start with a small amount for better control.
Gently drip vinegar onto the edges of a colored sugar mound and watch the fizz.
Repeat with different colors and patterns, allowing kids to experiment.
When finished, use a damp cloth to wipe the tray.

Notes

Supervise young kids closely during the activity, especially when handling vinegar and baking soda.
