Magic🎈Balloon ⚗️ Baking Soda Vinegar Reaction Kids Science 🔬⚗️⚖️ 101 🎥 Series 🎇

Balloon-Acid-Base-Baking Soda-Kids-Science-Experiment

Today, we are continuing our Science Series with this hands-on fun “let’s see what happens to our balloon” science experiment when vinegar and baking soda chemically react.  DSC_0218-2

What you will need:

  • baking soda
  • vinegar
  • balloon
  • a bottle (we are using a sake pot )
  • a funnel
  • science glasses (buy pink here  and blue here)
  • a tray and a mat to contain everything

Baking Soda/solid (NaHCO3) + Vinegar/liquid (HC2H3O2) → Carbon Dioxide/gas (CO2) + Water/liquid (H2O) + → NaC2H3O2


Science mystery revealed: baking soda and vinegar create an acid-base reaction of atom exchange, producing, as a result, the carbonic acid which is very unstable. Carbonic acid instantly breaks apart into water and carbon dioxide, the latter of which is gas. Gass needs a lot of room to spread out and the carbon dioxide starts to fill the bottle and then moves into the balloon inflating it.

During this chemical reaction between the base (baking soda) and the acid (vinegar), the resulting gas attempts to escape the bottle, moving up into the balloon because of the tight seal around the bottle. Because the gas has nowhere to go, it pushes against the balloon, inflating it!

p.s. It is very similar to when we exhale carbon dioxide to blow up balloons. (Adrian insists us do it at least once a day 🙂
