- tall drinking glass
- short drinking glass
- red and blue food coloring (or any colors you like)
- 3 tablespoons vegetable oil
Pour room temperature water into a tall drinking glass, leaving an inch of space at the top.
Add three tablespoons of vegetable oil and two drops each of the red and blue food coloring into the small glass. Do not add water to this glass. Carefully stir this combination a couple of times with a fork to just barely break up the drops. You want to have both small and large beads of coloring.
Slowly pour the oil and food coloring mixture into the water. Watch and in about 30 seconds the beads will begin to explode through the oil and release little red and blue streamers into the water. The streamers will appear as little fireworks!
I found this idea in a local grocery store advertisement, and it is really fun! The boys have already done 'fireworks' twice this morning! :)
