Halloween is the perfect time to try something a little different with the kids. This bubbling cauldron Halloween art activity is easy to set up, uses everyday items, and creates a really fun bubbling effect. It’s a great process art project that kids of all ages can enjoy.
To make things easier, I’ve included a free printable cauldron template you can use as the base for this Halloween art project.
What You’ll Need
- Printable cauldron template (PDF download below)
- White paper or card
- Dishwashing liquid
- Water
- A few drops of paint or food colouring
- Cardboard toilet roll (cut into small rings)
- Bowls or containers for mixing
- Newspaper or a Fitted Tablecloth to protect your table
How to Make your Bubbling Cauldron Craft
- Download the free cauldron template here.
- Print the cauldron template onto white card. If you only have paper, print it out and glue it onto card to make it sturdier.
- In a small bowl or tray, combine 1 tablespoon of paint with 1 tablespoon of dishwashing liquid. Add a small splash of water (about 1 teaspoon) and stir gently with a spoon or craft stick until the mixture looks smooth and foamy.
The mixture should be thin enough to bubble and stamp easily, but not so watery that it runs. Test a little on scrap paper first – if it feels too thick, add a few more drops of water. - Repeat for each colour you wish to use.
- Cut a cardboard toilet roll into small rings to use as bubble stamps.

- Dip a cardboard ring into the bubbly mixture, making sure the edge is well coated, and stamp it onto the paper, just above the cauldron, to make bubbling effects.
- Repeat with different colours and overlapping stamps for extra fun.
- Leave the artwork to dry completely.

Tips for Bubble Painting Success
- If the bubbles aren’t showing clearly, add a little more dishwashing liquid.
- Experiment with different colours for a vibrant Halloween art effect.
- For a shimmery, spooky effect, either mix a little glitter into the bubble paint or sprinkle some on top while the paint is still wet.
- This bubbling cauldron craft can get a little messy, so a Craft Apron and Fitted Tablecloth are handy to keep things stress-free.
- It’s a process art activity, so the fun is in the stamping, popping, and mixing colours.
