Will the colored vinegar stain my hands or clothes?

Liquid food coloring can stain light fabrics. Use small amounts and wear an apron. Rinse hands with water right away if color lands on skin. Most skin stains fade quickly with soap.

Is the reaction safe for young children?

Yes, when supervised. The ingredients are common household items, but you should watch for contact with eyes or mouth. Provide droppers that fit small hands and a tray to avoid slips.

What makes the fizz happen?

The fizz comes from a simple chemical reaction. Vinegar contains acetic acid. Baking soda contains sodium bicarbonate. When acid meets bicarbonate, they create carbon dioxide gas. That gas forms tiny bubbles that push foam outward. The color only travels with the vinegar, so change it to adjust the visual effect.

Can I use other acids instead of vinegar?

Lemon juice works but gives a different scent and a weaker reaction. Vinegar remains the most reliable for steady, gentle fizz.

How long will the colored vinegar last?

Store colored vinegar in small jars in the fridge for up to a week. Shake before use to remix any settled dye.
