One of the reasons slime is so fun to play with is that it acts like both a solid and a liquid. Pull hard, and it will break apart. Pull gently, and it stretches like a rubber band. You can squish it and bounce it like a ball, or relax your hand and let it flow out like a thick liquid.

How to make the blue fluffy whale-themed slime

The first step in this whale adventure is to create the slimy goodness to go with our whales. We (obviously) colored our slime blue, to create an ocean for our toy whales to “swim” in. But you could experiment with different colors. After all, the ocean blue isn’t just one shade of blue. The color can vary depending on the climate, weather, season, and even depth!

Try a teal blue, or maybe a darker blue. For best results, we used neon blue food coloring, and it gave us a very nice shade of blue for our whale games.

The secret to fluffy slime, rather than gooey slime, is in the shaving cream. Using a foam shaving cream with the basic slime ingredients helps create a more puffy slime, instead of watery.

And of course, kneading it together will help make sure everything gets mixed up well, and all the chemistry works.

Your kids will love the other fun ocean activities for kids – perfect for sea lovers!

Just like the ocean, this blue fluffy slime is a solution. The glue, sodium bicarbonate, and boric acid combine together to create a new whole in a small chemical reaction. And it’s perfectly safe kitchen science!

The sodium bicarbonate and boric acid combine to make “boronic ions”, which then combine with the PVA molecules in the glue. And that creates a reaction that not only absorbs heat (your slime will be cold!) but also creates a “non-newtonian fluid”.

This whale slime is also a perfect and simple chemistry experiment for your young whale lovers at home!

And voila! Your kids can now play with their blue fluffy whale slime right after!

¼ cup of water
1½ tbsp of contact lens solution with boric acid and sodium borate
