We tried out the milk and dish soap experiment I saw floating around the interwebs.  It is pretty cool!  My kids were definitely entertained and wanted to do it again and again.

Materials:

• milk (whole or 2%)
• Q-tips
• dish soap
• food coloring
• dinner plate or bowl

Fill the plate or bowl with enough milk to cover the bottom.  Then drop in some food coloring.

Dip a Q-tip in the food coloring to see what happens (nothing).  Then dip the Q-tip in dish soap and touch it to the food coloring.  Wow!  No need to stir, the colors will explode and mix on their own.
