Friday Fun Freetime: Explosive Art

Put 1 T baking soda folded into a square of tissue. Tuck it into a corner of a Ziploc bag. Mix 1/3 c vinegar and 1 t tempera paint. Pour into the opposite corner of the bag. Seal and shake slightly to mix. Put it on a large sheet of craft paper on the ground, and back up. Watch the bag explode, creating a design on the paper below. (Best done outside on the driveway).
