Materials
Large 2 ½ gal. Ziploc bag
Clear packing tape
1 cup baby oil
1 cup water with purple food coloring added
Directions
Pour the baby oil and the purple water into the Ziploc bag. Press as much air out of the bag as possible before sealing it. Run a length of tape across the seal of the bag and seal it again. Tape the bag on all 4 sides to the light table. If you don’t have a light table, it’s also fun to use a mirror, or even a glass sliding door, for a vertical experience! Once the bag is secured, encourage your child to use gentle fingers to move the water and oil all around the bag. As oil and water don’t mix, the two substances create an engaging sensory experience for the eyes!
