More Quick and Easy Halloween Science for Kids Anyone Can Do

Toil and trouble, boil and bubble!  This science experiment is great to add to a Halloween themed week.  Plus, the children will LOVE it! Have extras because they are going to want to do it again and again!

Here is what you need to make a Bubbling Witch's Brew!

  • Baking Soda
  • Vinegar
  • Liquid Dish Detergent
  • Halloween Themed Container (best if can be seen through)
  • Food Color
  • Flat Tray with short sides

Your super simple steps!

  1. Place container on the flat tray.  This will catch any over-flow.
  2. Ask one learner what color they would like the brew to be, red, blue or yellow.  Add that color to the container.
  3. Pour in some vinegar. 
  4. Add a little dish detergent. 
  5. Add baking soda.
  6. Ask different learner what color to add and add more baking soda. 
  7. TIP:  When the reaction stops being large add some more vinegar.
  8. Empty container and repeat!

What are some things you can talk about with this experiment?

Hypothesis: an educated guess.  Have learners look at what the supplies -- what do you think might happen?

Testing: Here is where you do the experiment. You can even test some of their ideas to show them what is going to happen.

The Results.

Chemical Reaction: Adding baking soda and vinegar creates a chemical reaction, a reaction that cannot be separated.  When they come together they create carbon dioxide.  This is visible through the bubbling reaction.  The dish detergent is added only so learners can feel the reaction.  Real life example: soda water

Color changes:  The food coloring is only for added learning and visual effects!  When primary colors are mixed together they make secondary colors.
