Picture of Goldie's Bubbling Halloween Cauldron
I made a piece that can be added to a cauldron to make it look like it is bubbling. This piece was made to fit around a person sitting in a large cauldron, so they look like they are submerged in bubbles or a hot liquid.

Step 1: Step 1

Picture of Step 1
I took a large round piece of cardboard and cut a portion out of the top and the bottom, that gives it an axe shape. The size you cut this will depend on the size of your cauldron and the size of the person whom sits in it. One portion that is cut out will go around their waist or chest and the other section will go around their legs.

That looks great. Great idea and project.

it looks like you have a second "fire" underneath. what is the base made out of?

where did you get the cauldron from?

The fire underneath is one of those old electric fireplace logs. The base is welded steel and the cauldron came from an old farm...it is real heavy!!!

The base is a welded steel frame. Underneath the cauldron is an electric log/fireplace thing that looks like it is burning.

I used these instructions with a slight variation (I'm putting a demon in the center of the "couldron") and it was very easy to do. A few recommendations from my experience: if you need the platform to be a bit more solid, glue two layers of cardboard together with the "grain" turned in different directions. I found that Target has something called "practice golf balls" which have holes in them like larger wiffle balls and these were a good size for smaller bubbles. The only problem I had was finding a way to easily cut the wiffle and practice golf balls in half. I ended up using small garden shears. They made it really easy, but be VERY CAREFUL since these are very sharp.

Thank you so much for sharing this project!

 This is great! I tried to make something similar once, a bio-hazard bucket that spilled over. Only I just used glow in the dark paint and lit it with a flashlight. I wished I had thought of THIS!!!!

I am new to the site and am having trouble figuring out how to post a question, so maybe one of you can help? First off, I loooove the cauldron!! I need to know if anyone knows how I can make those cheap plastic bats fly. Can anyone help me? Thanks so much.
This is delightful.

Every year I try to make something new for the kids this. Lava coming out of a grave. Last year I made a kid-ca-bob and every buddy thought it was great. This thing is great!!!!
this is a fantastic idea!

This is really cool! I'm building a big paper machie cauldron for this Halloween and this would go great in it. Put it down about a foot or so, then pump chilled fog over it. Or even better, put the whole thing on some sort of motorized turn table so it spins to look like the liquid is swirling around in the cauldron. Then add a stick to the spinning mass and attached the other end to a witch's hand. A nice stirring witch animatronic. I better get busy!

You should enter this in the "glow" contest.

Wow! This looks so awesome, the first picture you've got there on Step 1 totally fooled me (except the smile of course). Great job, and with enough time to implement before Halloween!

That's really cool! I've been looking for something to simulate lava or hot boiling liquid! I'm going to make a smaller one without the cutouts and with charred paper mache bones sticking out!
