Today, we are making green borax-free three-ingredient non-toxic slime inspired by the approaching St. Patrick’s Day. Slime, besides being absolutely awesome to touch, is also an amazing science demonstration. Besides, we love hands-on learning! And St.Patrick’s home-made non-toxic slime is just a perfect activity to get preschoolers and kindergartners excited about chemistry, science, and STEM. Most importantly, you can do it safely at home!
What you will need to make this borax-free three-ingredient non-toxic slime:
- 1/2 cup of liquid clear glue
- 1/2 teaspoon of bicarbonate of soda (baking soda) which helps slime firm up
- green coloring, confetti, and glitter (optional)
- half to 1 tablespoon of contact lens solution so that slime begins to bind (some use borax which also has some boric acid but we avoid using it since it is toxic.) Boric acid and sodium borate are the best slime activators
- Mix well with a fork until slime no longer sticks to your hands and the bowl.
HOW TO make St.Patrick’s Home-Made Non-Toxic Slime:
First, pour glue into a bowl. Then, add baking soda, glitter and liquid color (optional). Stir until uniformly distributed. Add contact lens solution last as it is an activator and once the slime firms up, it will be hard to add other ingredients. I suggest adding a squirt of the solution at a time until the slime starts coming off the sides of the bowl. Mix the slime with a fork and then knead it with your hands. If slime feels loose or too sticky, keep adding squirts of contact solution until it’s just right. (Be careful not to add too much of a contact solution, as it will result in slime becoming brittle, snapping and not stretchy at all.) If slime feels too hard, add a little more glue. Note: we do NOT add any water, otherwise, you will have to add much more contact solution to activate your smile!
