Directions
Cover a table with clear sticky contact paper (sticky side up) and then tape it down to secure it. Invite your child to stick coffee filters all over the contact paper. Fill a spray bottle 3/4 with vinegar and 1/4 water. Drop a scoop of baking soda onto the coffee filter. Place a drop of food coloring onto the baking soda as your child sprays the scoop of baking soda with the vinegar solution. Watch as the color baking soda fizzes. Allow the coffee filters to dry. Then remove them from the sticky contact paper.
