Through this simple activity, children can create and enjoy their own ocean world, waves and all! You’ll need just a few items: clear water bottles, water, a funnel, blue food coloring, baby oil (or a clear cooking oil), and small decorative items (sequins, pom-poms, glitter, tiny fish). First, place a funnel above each child’s water bottle and invite them to pour water through the funnel into their water bottle until it is about 2/3 full. Then, add a few drops of food coloring and baby oil, leaving room to add in some decorative items. Encourage the children to use their creativity and imagination to add ocean-themed decorations to the bottles. Once complete, close up the bottles, seal them tightly and show the children how they can shake their sensory bottles to watch the waves in the ocean they created flow.
