Ok, I’ll admit…they’re more like diving beans than they are jumping, but who ever heard of magic diving beans?
Here’s a great little science experiment you can do in your own kitchen with ingredients you already have on hand. This is all you will need:
- Tall clear vase
- food coloring
- 1/4 cup vinegar
- 3 tsp baking soda
- beans (or rice, small pasta, etc)
Fill the vase with water, leaving about two to three inches of head room at the top. Add a few drops of food coloring and stir to color water. Put the 1/4 cup vinegar in and then add the baking soda 1 teaspoon at a time. Note: Mixture will bubble and foam…watch for overflow.
After the last of the baking soda is in, add some beans. Wait a few minutes and the beans will start to rise to the top…then sink…then rise again. Some will make it halfway down before they change their minds and swim back up. The beans will be surrounded by bubbles that will help steer them. Now granted, they don’t do this with lightning speed, but it’s still fun to guess which ones will take a dive next. And it’s a great way to keep the kids (or husband) amused for at least five minutes. 🙂
