From the desk of the product designer:

Behind the design

In early designs, we were planning on having kids just pour the water into the cauldron to set off their chemical reaction. But that made a real mess during testing! So we came up with the built-in pump system to help direct the flow of water. That way, you can keep things tidy and add a dose of mystery to your spooky display!
