Oil and Water Project. Wow...I did this the other night with my niece and we called it "ocean in a bottle." Vegetable oil and water and food coloring. Cutest thing ever. She added little jewels and fish and was so proud of her ocean bottle! #ad
So another great project for kids. This one is called a lava lamp...same technique. Fill water bottle with oil, food coloring, and water. Is this not cool or what? Kids can add gems, little fish, or anything to make it personal.
