My 3 year-old had a blast "painting" snow at our kitchen table yesterday. What you will need:
Snow
Container to hold the snow (preferable plastic)
Food coloring
Paint brushes
I took a glass baking dish (because my plastic containers were dirty in the sink!), and filled it with snow. Then I took blue, red and green food coloring, placed the colors in separate bowls and mixed with water.
My 3 year-old had so much fun sitting as the kitchen table "painting" the snow. He sat there for about a 1/2 hour painting, mixing the colors and then playing with his hands.
This was a fun snowy day project that allowed us to stay inside, when all my little guy wanted to do was play outside in the freezing cold! :) Hope you and your little ones have fun as well!
