You CAN NOT make your own saline solution with salt and water. This will NOT work for slime!
Borax (sodium tetraborate) and baking soda (sodium bicarbonate) aren’t the same thing. They’re both salts, and they’re both popular as “green” household cleaning agents, but borax has a pH of 9.5, compared to baking soda’s pH of 8. This makes borax considerably more alkaline than baking soda.
