I just made this for a halloween party with my kids. Happy to share the information!^^ I tried to find a how-to on here first and didn't have any luck, so hopefully the next person who needs this recipe will be able to find this post.

Pharmacies here usually sell borax(붕사) because it's used to kill cockroaches (yikes).  Luckily, you'll need less than half a teaspoon in your slime, so it's nothing to worry about.

Good luck to anyone who's looking to make slime with their kids! Mine loved it
