Remember the bubbling swamp water of this month’s Kids’ Korner story? Well, here’s a way to enjoy the power of bubbles at home (without the slime)!
What you Need
- A tall narrow clear glass (a tall narrow vase will work, too. But don’t use a mug, ‘cause it won’t work)
- 1 cup of water
- 1 Tbsp. baking soda (the old stuff in the fridge is okay)
- ½ Tbsp. white vinegar
- small amount of lentils
- small amount of Craisins (dried cranberries)
- clear soda like 7-Up, or seltzer water
- elbow macaroni
- popcorn kernels (not the microwave bag kind)
What you do
- Pour the water into a tall narrow glass.
- Mix in the baking soda until dissolved
- Drop in some lentils, then slowly add the vinegar.
Why It Works:
The chemical reaction will cause bubbles to form, which will lift the lentils to the surface, making them dance. But after a little while, the surface tension will keep the lentils floating on top, so add 5 or 6 Craisins, and watch them dance around. If you don’t get enough bubbles, slowly add a little more vinegar.
Alternate Ingredients: You can get the same effect by using clear soda or seltzer water, instead of the water, baking soda, and vinegar. Try dropping in some elbow macaroni—and see which one works best! It’s fun for kids of all ages.
