Halloween is just around the corner, so there's no better time to do something spooky. witches potionsPotions are a much-loved activity any time of year in our house, but especially at Halloween! Check out this collection of fizzy potions, slime potions, color-changing potions, and even dry ice potions and let us know if you try any of them out!
Teaching with potions
Brewing potions is a great activity just for fun, but it can also include many learning opportunities.
The BEST witch potions
Effervescent Witch's Laboratory
Effervescent potions They are easy to make with baking soda and vinegar and they look very impressive. I made a fizzy witches lab for my daughter and she loved it.
I used test tubes rather than larger containers as it meant I could easily experiment with different colours and allowed me to make lots of eruptions with just a small amount of baking soda and vinegar.
What you need to make fizzy potions
Baking soda (sodium bicarbonate)
Colorful food
Vinegar
Test tubes or other containers
Pipette
Water
How to make fizzy potions for witches
Place a teaspoon of baking soda, a little water, and a few drops of food coloring in each test tube.
Use the pipette to add vinegar to each tube. The mixture should bubble and come out of the test tube.
BETTER ADVICE – To make a foamier potion, add a little dish soap before adding the vinegar.
Experiment with different amounts of baking soda, dishwashing liquid, and vinegar to find the perfect fizz!
Spider slime
This stretchy slime has a great texture and is super easy to make. It can be squished, stretched and poured, and has a deliciously slimy and gooey texture!
What do you need:
chia seeds
PVA glue
Cornmeal
Water
How to make spider slime
Soak the chia seeds in water for a few hours.
When the chia seeds look thick and sticky, add a tablespoon of PVA glue and enough cornflour to make the mixture thick and sticky. For a drier dough, add more cornflour.
If you are worried about kids trying to eat the slime, you can skip the PVA glue as it doesn't stretch as well.
Magic potions that change color
Color changing potions Using red cabbage indicators is a great introduction to acids and alkalis. Kids can experiment to find out how many different colors they can create!
To prepare the red cabbage indicator, simply boil the red cabbage in water for about 5 minutes. The water in the red cabbage is the indicator and changes color depending on whether an acid or alkali is added.
I used vinegar, lemon juice and baking soda to create the colors below.

Goblin Snot Juice
We share some easy potion ideas with Day out with the kids A while ago. Including creepy Goblin Snot Juice And a color-changing bat!
This potion is green water with a layer of oil on the surface. If the container is shaken, the mixture separates back into oil and water.

Witch's Density Flask
This witch density jar is made in a similar way. Just pour colored water into a jar with a layer of oil on top and then try to find different spooky objects to float in the layers.
We found an eyeball bouncing at the top and a coin sank to the bottom.
