Fizzy Bubbles is a simple science experiment combining the excitement of cause and effect with a sensory surprise. This experiment puts a fun twist on the common baking soda and vinegar reaction best known for making volcanoes. By adding a powdered drink mix such as Kool-Aid or Gatorade to the baking soda, as the reaction happens, the bubbles will change color and release an awesome smell. I like to use Cherry Kool-Aid, because it creates bright red bubbles and it smells amazing! Most powdered drink mixes go unnoticed in the baking soda until the reaction happens, making the experience a fun surprise as well as an exercise in cause and effect. The child’s understanding that one event brings about another will stimulate their curiosity leading to greater discoveries and a sense of control over their world.
Here are a few tips for doing the Fizzy Bubbles experiment with children:
- Use a disposable table covering for easier clean up.
- Have children wear aprons to protect clothing from stains.
- Mix different drink mixes to create new colors and scents.
- Experiment with other safe to use household acids to compare which causes the powder to bubble the most. Other household acids include: apple cider vinegar, lemon juice, lime juice, orange juice and tomato juice.
- Prepare a variety of liquids to test the powder. Use some that will react, and some that will not and make a hypothesis about which liquids will create a reaction and which liquids will not.
- Invite the child to ask questions! Their questions may reveal new interests you can pursue together.
- To challenge fine motor skills, try using pipettes or a squirt bottle to apply the vinegar.
