DIY Smoke Bubbling Cauldron

This DIY smoke bubbling cauldron is sure to make the other witches in your neighborhood green with envy. Read on to learn the secret!

A really good witch’s brew needs a great many things.

In addition to your standard “Eye of Newt” and “Wing of Bat,” there are the more subtle ingredients like “Bottled Fart of Mottled Frog” and “Exasperated Sigh,” the latter only found in married women.

Then there are the esoteric and the arcane like “Fool’s Whimsy,” which if improperly handled can have ruinous consequences for both witch and bewitched or “Whirled Peas,” an ingredient so rare and so volatile that no witch in living memory can truthfully claim to have seen it or handled it.

But needs must or cauldrons rust, so a resourceful witch muddles through with what she has and improvises what she doesn’t.

Fortunately for me, my babes – who has been known to dabble in green skin and warts from time to time when September chills into October – has come up with a fabulous new witch’s brew that requires nothing more exotic than “Juice of Fog” and “Solution of Bubble.”

Of course, like all crafts, witch or otherwise, there is some specialized equipment involved, but if you want to serve up the best brew on the block, you’re going to want to read on.

To add to the effect, I’m also going to show you how to make a faux glowing ember fire to put underneath your cauldron.

And as for the witch? Well, you can use any old hag you desire. We got ours from Home Depot back in the summer, but they’re pretty much interchangeable.

DIY SMoke Bubbling Cauldron Tutorial

Step 1 – Make a faux fire

Before we get to the smoke and bubbles, let’s build a fire for old Hagatha Christie.

I started by placing some small birch logs around a wire wreath form. This step isn’t necessary, but I think it looks great. Then I sprayed just enough spray foam around the form to hold the logs in place.

Before the foam hardened, I placed a string of orange battery-operated LED string lights around the foam.

I followed this with just enough additional foam to cover the lights.

Step 2 – Paint the fire

The next day, I painted the foam with flat black and gloss red spray paint.

Step 3 – Secure the hag

Our witch came with nothing more than a flimsy pole to secure her in the ground. With every puff of wind she turned like a ballerina. To solve this and keep the witch tending to her cauldron, we zip tied her to a narrow garden trellis.

Step 4 – Cut the cauldron

I cut a square hole in the back of the cauldron with a utility knife to allow the foggy bubbles a way into the cauldron.

Step 5 – Ready the fog bubble machine

I filled the fog bubble machine with fog juice and bubble liquid. After trying a few different types, we found concentrated bubble liquid diluted to work with bubble machines (ratios vary by brand) produces much better bubbles than the standard bottles of bubble liquid sold with those little plastic bubble maker rings in them.

A successful test run!

Step 5 – Add lights

I first coiled a Govee outdoor rope light and set it on green, but I later swapped it out for Govee flood lights set to green. Any green outdoor lights will work.

When darkness falls, the witch starts to brew!

Still images don’t do the cauldron justice, so I encourage you to watch one of the social media videos at the beginning of the post!
