Make an Ocean in a Bottle
Materials
Mason jar (we like this set from Amazon)
Vegetable oil
Water
Blue food coloring
Directions
Fill your container 1/2 way with water and add as much blue food coloring as desired
Fill the rest of the container up with baby oil or vegetable oil. Try and fill the container as full as possible, reducing the amount of airspace that will be left after you screw on the lid or cap.
Cap tightly
To make a wave tilt and gently shake your ocean in a bottle! Watch the wave action in your sea.
