Glowing, No-Mess Slime (yes, No Mess!)

Need slime as part of your Halloween décor but don’t want to deal with the mess? This shapeable glowing slime can be molded into almost any form, lights up for your nighttime display, and it’s easy to pack away after the holiday is over.

You’ll need: (affiliate link proceeds earned on my blog are donated to no-kill animal shelters and rescue organizations):

Chicken wire, spray foam insulation, and green string lights

A drop cloth, florescent green spray paint, and protective gloves

First, form the chicken wire into your desired shape.

I want to make it look like slime is running down some steps so I’m bending the wire to fit each angle.

Place the formed chicken wire over a drop cloth and lay the green string lights so they cover the surface. Ensure the outlet end is pulled out and away from the wire.

Using protective gloves, spray the foam insulation all over the wire and the lights so that everything is fully covered. Spray in a random pattern so the foam looks like oozing slime.

Allow to fully expand and harden. This will take a few hours.

Once dried, use the florescent green spray paint to lightly coat the surface.

After the paint has dried, set your finished slime back onto the spot where you want to display it and place additional props around it as needed. Your slime will look creepy during the day…

…and glow an icky green at night.

    Nice effect and love your dog so cute! Didn't your trick or treater's crush the little green lights as they walked up to your door to get candy? What I really want to know is how you can bend wire, spray it will foam insulation and then spray paint it all without getting insulation and paint splattered all over your high heel shoes? Your a better women then I am. I usually work in my old crocs or tennis shoes so if they get ruined not a no problem.

    Is that stuff biodegradable or recyclable, or will it end up in the landfill?
