Best fizzing baking soda vinegar painting kids experiment that creates beautiful color mixing reactions for toddlers, preschoolers, and kindergarteners.
How about some scientific sensory fun? For instance, your little one will be fascinated with this colorful, fizzing baking soda and vinegar painting experiment! Besides, who would not want to paint with colored vinegar on baking soda, creating bursts of colors? Most importantly, the set up should take you less than five minutes as you need only two ingredients for this fizzing baking soda paint kids science experiment!
What you will need for this fizzing painting:
- a tray
- baking soda
- food coloring
- little cups (we are using this mini measuring beaker set)
- different droppers (we love using silicon ones or glass dropper pipette and also turkey baster that holds more volume)
- science glasses (buy pink here and blue here)
HOW TO conduct this kids science experiment:
First, sprinkle baking soda on a flat dish or a water-proof tray, enough to cover the surface. After that, pour vinegar into beakers or small cups and add various food coloring – one color per beaker. Thereafter, offer your child droppers to pour vinegar over the baking soda.
Baking Soda/solid (NaHCO3) + Vinegar/liquid (HC2H3O2) → Carbon Dioxide/gas (CO2) + Water/liquid (H2O) + → NaC2H3O2
Science mystery revealed: Baking soda and vinegar react with each other because of an acid-base reaction. Note that baking soda is a base while vinegar is an acid. So, when they react with each other because of an atom exchange, they form carbonic acid which is very unstable. Besides, carbonic acid instantly breaks apart into water and carbon dioxide. Most importantly, the latter is the gas responsible for all the fizzing as the gas escapes the solution. Thus, when baking soda receives a proton from vinegar, it transforms into water and carbon dioxide molecule. Consequently, since carbon dioxide molecule is now free of its other chemical bonds, it can escape, bubbling forth as a gas. As a result, this chemical reaction releases gas which bubbles and fizzes, making it a fun sensory acid-base kids experiment.
Adult supervision is required.
