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
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.
Step 2: Step 2
I covered the cardboard with aluminum foil. I cut wiffle balls and round styrofoam balls in half and then hot glued them to the cardboard base, these will represent bubbles in the cauldron. (I would recommend using all wiffle balls of various sizes and eliminate the styrofoam balls.) I used orange christmas style lights and then attached them to the board and tucked them into holes of the balls. I attached them with 2" boxing tape, you may want to attach them with something else. I have one set of lights set to flash and one set to stay on constantly. It is important to put in the flashing light bulb before the next step.
Step 3: Step 3
Turn the lights on and see if you like the arrangements of your lights. You may want to move some of them around if you have too many lights in one area. If you are happy with the arrangement and how the lights flash then proceed to the next step.
Step 4: Step 4
You will need a can of Foam Insulation Great Stuff. Make sure you put on some latex gloves to protect your hands. Place your project on some newspapers to protect everything else from the Great Stuff. Add the Great Stuff and let it sit and dry.
Step 5: Step 5
After it dries you can plug the lights in and see how it looks. It should have a lava look to it. After dried I also added some paint. I used some craft paint and lightly and randomly added orange, yellow and small spurts of black. I do not have a picture of that step, but it makes a big difference of the final look and the colors that it glows.
Step 6: Step 6
When dried add to you cauldron and make sure you have a good fit. If everything looks good, just plug it in, add a body and you have yourself a victim for your witch to cook.
