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!”

This was a total hit! I appreciate the debugging right in the booklet as well as how to keep the fun going with your own materials.

My grandkids had so much fun! Their parents turned it into a homeschool lesson and the oldest explained the chemical reaction to me as the youngest took a turn pumping the brew in the cauldron.

My daughter really enjoyed being able to decorate her own Spooky scene for the Halloween Bubbling cauldron. Directions were easy to follow. I love how everything is included in the box.
