Styrofoam Ice & Blue water beads with penguins.
Using Broken pieces of Styrofoam box as ice capsules for the penguins to sit on & bright blue water beads as the water Dimples played in the penguin sensory box for hours.
Like as if it were in water the Styrofoam didn't sink in the water beads. It was a fun experiment and we talked about where the penguins lived and how they lived on ice capsules and were able to escape from predators who live in the water like killer whales and lion seals by jumping up onto the floating ice. Happy feet the kids movie came into our conversation a few times because the penguins are off this movie and Dimples adores the movie.
Eventually he broke the Styrofoam up into small pieces for each of the penguins but they still wouldn't sink or stay under the "water". I also put in some foam packing that you get in delivery boxes and the water beads made it do strange things. this was something interesting for Dimples as well, the pieces stuck together and got some what sticky so through play they ended up slightly touching each other and eventually clumped together.
Dimples loves water beads, he never gets bored of them.
