When you live in a rainy city you have to find new ways to keep your little ones busy. Today my daughter asked me to make "Goo" so we did. The recipe is simple; 1 part corn starch, 1 part water, food colouring, mix and have fun! We used up our old green food colouring for this project, (we don't eat this stuff anymore) If you want to get experimental try using natural food colouring from pickled beets, turmeric or berries. This Goo is fun to play with and clean up is easy, my four year old spent the better part of the morning playing happily with the stuff!
