Ocean Slime Supplies
Let's take a look at what you will need to whip up a batch of under the sea ocean slime.
- Small bowl
- Clear glue (5 oz bottle)
- ½ cup water
- ½ tsp baking soda
- 1 tbsp saline solution
- Soap colorant (we used a mix of neon blue and navy)
- Blue extra fine glitter (we mixed a light blue and a dark blue but any blue works)
- Clear fishbowl beads
- Plastic toy fish
- Airtight plastic container
You will notice that we used soap colorant to color our ocean slime. I would recommend you use soap coloring rather than food coloring as well because it doesn't dye your hands like food coloring does sometimes. Plus, there are a ton of colors to choose from!
How to Make Ocean Slime
1. Combine glue and water in a small bowl.
2. Add a few drops of blue coloring (we mixed a bit of navy with neon blue). Stir to mix well and add in additional drops of coloring if desired.
3. Add baking soda and stir to combine.
4. Next, add some glitter.
5. Then, add the saline solution. You will see the slime instantly begin to form.
6. Pour some clear fishbowl beads and slowly add more to make it the consistency that you want.
7. At this point the slime will be very sticky– but don't panic! Just mix the slime in the bowl until it becomes more formed. Once it is a bit more formed knead the slime a bit until it is no longer sticky.
8. Add a few plastic fish into the slime and then it is ready to be played with!
Once you are done playing with your under the sea slime place it into an airtight plastic container for storage until your next play session.
