Chemistry Experiment For Kids – Make a mini jet boat from a chemical reaction

chemistry science experiments for kids

In this chemistry experiment for kids, we will see how to make a jet boat with the help of baking soda! Some products react together and produce a new element. In this experiment, the new element produced is gas.

How do we turn this gas into a source of energy to propel our boat? The easiest way is to store the gas under pressure. When the pressure is released, the boat will be propelled forward.

Chemistry experiment for kids equipment:

  • A boat-shaped piece of plastic or wood
  • A large empty bottle of aspirin
  • A straw
  • Vinegar
  • A Stanley knife
  • Adhesive tape
  • A tissue
  • Baking soda (available in pharmacies)
  • Aluminium foil

Chemistry experiment for kids instructions:

  1. Remove the cap from the bottle of aspirin and make a hole in it the diameter of the straw. Insert the straw and seal around it with glue. Cap the end of the straw with aluminium foil.
  2. Fill a quarter of the aspirin bottle with vinegar.
  3. Put 3 or 4 pinches of baking soda in the tissue. Place the tissue on the top of the bottle.
  4. Close the bottle and quickly attach it to the plastic or wooden boat with adhesive tape. Shake the boat to mix the baking soda and vinegar and then place it in a bathtub filled with water. When the pressure is too high, the small aluminium foil cap on the straw will fly off and the gas will propel the boat forward!

Chemistry experiment for kids explanation:

Baking soda and vinegar create a chemical reaction that releases gas. Why does this mixture produce gas? The reaction of baking soda and vinegar is actually the result of two reactions.

The first reaction relates to acids and bases. The second reaction is caused by the decomposition of the element produced in the first reaction. This element is carbonic acid, the product of the reaction between the hydrogen ions of the vinegar and the ions of the baking soda. The second reaction is the result of the decomposition of the carbonic acid, which is then turned into carbon dioxide.
