Having fun with paint and marbles!!! All you need is some liquid paints, construction paper (any color), a baking sheet, tape, and a marble. Just take the construction paper and tape it to your baking sheet (just 2 small pieces will do for each side). Place a couple dollops of paint anywhere on the construction paper you like. Then place the marble on the construction paper and start tilting and moving the baking sheet around to get the marble rolling. Do this until the marble is no longer making a trail of paint. Luckily we did this on the porch since the boys got excited and the marble went flying out of the baking sheet a couple times!
