25. Dancing Rice

Science Experiments To Try With Your Kids 3

Materials and instructions needed for the experiment taken from Buggy and Buddy:

  • Clear container
  • Water
  • Baking soda
  • Vinegar
  • Rice (We used a short grain brown rice.)
  • Spoon
  • Optional: Food coloring


  • Pour one cup of water into your clear container.
  • Add 1 teaspoon of baking soda to the water and stir.
  • Sprinkle some rice into the mixture.
  • Add 1 tablespoon of vinegar to the water. The vinegar reacts with the baking soda in the water creating bubbles of carbon dioxide.
  • In the next few minutes the rice will begin to “dance”. As bubbles of carbon dioxide adhere to the rice, the rice is brought up to the surface. Once it reaches the surface, the gas is released, and the rice falls back down again.

26. Kids Cloud Experiment

Make sure you keep the cotton balls wet during the whole experiment, which usually takes approximately one week when the bean spruce and a small beanstalk appear.

29. Skettles Experiement

Science Experiments To Try With Your Kids 7

Your kids could enjoy this fun rainbow experiment with their favorite candies.


  • Skittles
  • Hot water
  • A shallow dish

Place the candies along the inner perimeter of a plate. There is no particular order for the colors. You can try in different order anytime you want to practice this experiment.

Once you place the skittles, it is time to add the hot water to the center of the plate. Make sure you add water without floating the candies.

You will notice immediately how the outer shell of the candies cracks and dissolves and creating a mesmerizing rainbow effect.

Hope these experiments will bring in a lot of fun and knowledge to your kid’s life!
