Sublime Slime!

May 04, 2020

Who doesn’t love slime? It is so much fun squishing, stretching and letting it ooze though your fingers. You can have hours of fun playing with this stuff. This is the basic recipe, but you can make it stretchier, sparklier, puffier or more tactile by adding a few ingredients.  There are multiple recipes available for all sorts of cool slime.




  • 6 ounces of liquid glue

  • 1/2 tsp of baking soda

  •  tbsp of contact lens solution with boric acid

  • Optional - Food coloring for a dazzling slime

  • Optional - Add in glitter for a sparklier slime

  • Optional - Add 2 tbsp to up to 1/2 cup of water for a stretchier slime





Pour your entire 6 oz glue into a bowl. I like Elmer’s glitter glue. Add your baking soda and mix in well. If you would like food coloring and glitter, you can add them now. Slowly add in your contact lens solution by teaspoon and mix well.  You may not require the full amount. You will see your slime ball form and stick together. Now take it out of the bowl and play with it. The more you play with, the better it gets! If you find it too sticky, you an add a little more contact lens solution. And voila…you have slime! Now you can start experimenting with other ingredients.  


Here are some safety tips recommended for slime: Adults should supervise the slime making and handle all chemicals. If you have sensitive skin, you might want to wear gloves while playing with the slime. Always wash hands before and after use.  If you notice any skin irritation discontinue use. If irritation persists, consult your doctor.
