Ocean Slime Activities
Ocean slime is stretchy, squishy, gloriously messy, and preschoolers cannot get enough of it.

These ocean foam activities are wonderfully messy, highly visual, and perfect for setting up outside on a warm afternoon. Preschoolers can scoop, squish, and splash to their hearts’ content.

They are great for quiet time, car rides, or just a change of pace from the bigger bin setups. These ocean sensory bottle ideas are simple to put together and endlessly fascinating for preschoolers to shake, swirl, and watch.
