St Patrick’s Day Green Slime Recipe
Supplies
• 1/2 cup clear PVA school glue
• 1/2 cup water
• 1 tablespoon saline solution (must contain boric acid and sodium borate)
• 1/4–1/2 teaspoon baking soda
• Green food coloring
• Glitter or sequins
• Gold coins
• Confetti (optional)
• Small black pots (optional)
Instructions
Step 1
In a bowl, mix 1/2 cup glue and 1/2 cup water until completely combined.
Step 2
Add green food coloring and glitter. Mix well to distribute the color and decorations.
Step 3
Stir in 1/4–1/2 teaspoon baking soda. Baking soda helps the slime firm up and form properly.
Step 4
Add 1 tablespoon saline solution and stir until the slime begins to pull away from the sides of the bowl.
Step 5
Knead the slime with your hands until it becomes smooth and stretchy. If the slime feels sticky, add a few more drops of saline solution and continue kneading.
Tip: Placing a few drops of saline solution on your hands before kneading helps prevent sticking.
Once the slime reaches your desired consistency, stretch it, squish it, and enjoy your St Patrick’s Day slime.

The Science Behind Slime
Making slime is a great way to explore simple chemistry concepts.
When you mix slime activators such as saline solution, borax powder, or liquid starch with glue, a chemical reaction occurs. The borate ions react with the PVA glue molecules, linking them together in a process called cross-linking.
This creates a stretchy substance known as a polymer.
Because slime behaves partly like a liquid and partly like a solid, it is called a non-Newtonian fluid.
Kids can explore concepts such as:
• polymers
• mixtures and substances
• elasticity
• viscosity
• states of matter

Hi. I’m doing a science fair and I want to do slime. My testable question is “ does sta-flo or tide affect the stickiness if slime affect it on different surfaces
Feel free to email me sarah@littlebinsforittlehands.com if you want to talk it through.
Hi,
Thank you so much for the plethora of wonderful STEM/STEAM experiences for children that you have created. I have purchased many and look forward to the new information to come.
As an Early Childhood Educator, teaching a group of 18 PreK children with my co-teacher, I am always striving to learn.
However, I wanted to point out an error in spelling. In your St. Patrick’s Day STEM Pack, specifically the Green Carnation Challenge, the title is written “DIE A CARNATION GREEN CHALLENGE”. The word “die”, which means “of a person, animal, or plant, stops living” and should be spelled DYE, “a natural or synthetic substance used to add a color to or change the color of something”. I am assuming that this was a oversight, and I wanted to make sure you knew.
Once again, thank you so much for all that you do. I really enjoy your effort to support the education of young children.
Sincerely,
Linda Oxman
