You are watching: How to make slime without borax or baking soda or cornstarch


It was my 5-year-old who introduced me to homemade slime via YouTube — something she’s allowed to watch during her allotted screen time. I was surprised by how easy it was to make. The first recipe we tried involved Borax, something I had on hand from an experiment in making my own laundry detergent (this was before I had two children, obviously). The resulting slime was fine, but smelled noxious and I ended up throwing it away after about an hour of play.

Repeated requests for more slime led me down a rabbit hole of slime recipes — slime made with yogurt, another with cornstarch and glue, and a disastrous batch made with shaving cream. Either the recipe didn’t hold up well to play or they didn’t work at all. That’s until we found this one. This slime recipe calls for just three ingredients — school glue, baking soda, and contact solution — each of which we have on hand at all times.

Fair question, dear reader. Consider slime an example of one of the many non-cooking projects that happen in the kitchen. Making slime, like making pasta, is one of the ways I engage with my kids in the kitchen. Plus making slime is fun (and a great activity to do during winter break). You’ll be surprised how quickly the slime comes together and how long your kids will play with the slime afterwards.

Because the winter is loooooonnnnnggg. Slime is an ideal quiet-play activity. We can mix some up and I can work next to them at the kitchen table while they play.


Borax is a popular ingredient for making slime, but beyond my own negative experience with stinky borax-based slime, there is pause for concern in using Borax to make slime. Borax is a chemical cleaner and unchecked repeated and prolonged exposure to it is bad for your skin and potentially bad for your health. This is paraphrasing from a box of Borax.

Several news articles have suggested that Borax play is fine in small doses, if the Borax is diluted and everyone wears gloves. Personally I’d rather not take any chances and use this baking soda and saline solution instead. Besides, it makes a more supple and easy-to-squeeze slime.
