Science in the Kitchen

This was so much fun to do with my niece, and nephews when they came over for a visit one day. Even my little two year old had fun participating (eating the raisin) :) Everything I used was straight from my kitchen cabinets. The only out of pocket expanse was for the 7up which came in handy for our thirty scientist. 

I set these experiments up just for some cheap entertainment for my niece and nephews who rang in age. This would also make a great educational tool for homeschooling children, or even a mad scientist birthday party.
