Halloween Slime Ideas

Slime was a toy product manufactured by Mattel, sold in a plastic trash can, and introduced in February 1976. It consisted of a non-toxic viscous, squishy, and oozy green or other color material made primarily from guar gum. Different variations of Slime were released over the years, including Slime containing rubber insects, eyeballs, and worms.


I don’t know what it is about slime that kids (and adults) love so much. I guess it must be the satisfying squelch between your fingers as you play with it – like a kinetic stress ball!

Not only that, but there is a science behind making slime, so it can be used as a mini science lesson at home.

When I made slime for the first time I was in awe at how it changed with every step – and that’s me as an adult. For kids it is like magic!

Slime has excellent sensory qualities – which is great for kids and those with anxieties. It can be a calming object to play with, as you focus on the sounds, texture, and smell of the slime.

Halloween slime (and slime in general) can be made in several different ways, and I’ve rounded up an awesome selection of different Halloween slime ideas that you are going to just love and have so much fun making!

Once you know how to make a basic slime recipe then you can really make it your own for the spooky season by making it in different colors and adding different objects to it! Like googly eyes, Halloween glitter and confetti shapes, and even little plastic spiders and bugs!

The first slime on the list below is one I made for Halloween – the rest of the ideas are from talented bloggers around the world. These links open in a new tab, so remember to hop back over here to go through the rest of the list.
