What you get

Discover spooky science — with your very own bubbling cauldron. Design a felt witch and construct the witch’s lair, complete with a cauldron connected to a hidden pump. Mix together a witchy brew using citric acid and colored baking soda, use the pump to add water, then watch your cauldron bubble and boil in a creepy chemical reaction!
