Walking Water experiment and Pi

    Today has been the first really sunny day in over a week here.  We had lots of rain last week, which meant the boys were stuck indoors all week.  They finally got to go outside today and run around, climb the tree and ride their bikes.  Back inside though, we decided to celebrate Pi day and do an experiment.

    First, we made pie.  Ok, I made pie.  Cherry and strawberry pie.  I used the double pastry recipe from the Better Homes and Gardens cook book, 1 can of cherry pie filling, and a handful of frozen strawberries.  The result was delicious.
Pi day= pie
After enjoying the scrumptious pie, repeating to each other the ratio of a circle's circumference to its diameter: 3.14159265, we decided to try a fun experiment called "Walking Water", found on  kidspot.com.  You can find the directions on the website, but I'd like to share photos and a video of our experiment.
We took 3 bowls. 2 bowls we filled with 1 cup each of water.  In one bowl, we added 2-3 drops of blue food color.  The other we added yellow food coloring.  The 3rd bowl was placed in the middle with no water.  
We took a folded paper towel and draped it from the blue bowl to the empty center bowl.  We took another paper towel and draped it from the yellow bowl to the empty center bowl.
The boys watched in awe as the water "walked" from their bowls and into the middle bowl.
The video is about 2.5 minutes long and too big to load to the blog, so I am adding a link to it on youtube.  Walking Water
