Tips for the Best Edible Slime Experience
One-time play: Because it's edible (and sticky!) this slime is meant for same-day fun. Snap a few pictures to capture the magic before it’s gone. Work carefully with hot marshmallows: Melted marshmallows can get really hot straight out of the microwave. Make sure an adult is handling the bowls and stirring at first.
Go slow with the corn starch: It’s tempting to add a lot at once, but too much can make your slime stiff instead of stretchy. Add just a little at a time! Knead, knead, knead: If the slime feels sticky, kneading it with your hands will help smooth it out and make it super stretchy.
Reheat if needed: If your marshmallow slime starts to harden during play, pop it back in the microwave for about 10 seconds and it’ll be good as new.
