Kid Science: Fireworks in water

In the spirit of July 4th and the fireworks tradition, here is a fun project to do with the kids where you make "fireworks" in the water.

The supplies needed are:

1.  Clear jar:  a mason jar works well
2.  Another small container
3.  Vegetable oil (or other cooking oil)
4.  Food coloring

Fill the mason jar mostly full with water.  In the second small container put just a little bit of vegetable oil.  A few tablespoons will be fine.  In the oil, put 4-5 total drops of food coloring.  Each drop should be a different color for the best results.  Take a fork and mix the oil up which will turn the food coloring drops into a bunch of small droplets.  Now slowly pour the oil solution into the jar of water.  Pour it very slowly so the oil and food coloring stay on top of the water.  If you pour too fast the color droplets will immediately enter the water all at one time and the effect will not work.  Now just enjoy the "fireworks."

Have a safe and fun 4th of July!
