The next step in this 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!
Kindergarteners will love these whale activities. Perfect for early learners who love whales!

Try a teal blue, or maybe a darker blue. For best results, we used a 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.

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”.

One of the reasons slime is so fun to play with is because 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.

Now for the actual ingredients. You’ll need:
- ¼ cup of water
- ½ tsp of baking soda
- 1½ tbsp of contact solution (make sure it has boric acid and sodium borate in it!)
- ⅔ cups of white Elmer’s Glue (or any other PVA glue)
- 3 cups of foaming shaving cream
- ~10 drops of neon blue food coloring
You’ll also want to have:
- a large mixing bowl
- a mixing spoon
- plastic place mats or table cloth (for easy clean up!)
- whale toys or figurines
- baby oil (optional, but nice to have!)
Here’s what you do:
- First, pour the glue into the mixing bowl. Add the water, and mix well.
- Add in the baking soda and mix.
- Spoon in the shaving cream and stir.
- Add the food coloring. Stir well until the slime is completely blue!
- Now for the fun part: slowly add in the contact solution and stir. Keep stirring until you get the fluffy slime consistency you want.
Pour out the slime onto the plastic mat and hand knead it. Be patient! It takes a while to get the slime to stop feeling sticky and feel fluffy and soft and easy to work with. If you feel the need, use a little bit of baby oil to keep the slime from sticking to your hands while you knead.
After kneading for a few minutes, you should see the blue fluffy slime your kids will love to play with. Just add whale toys and kids and watch the fun!
