Bubbling brew, take two

Bubbling Wizard's Brew is fast becoming my go-to science experiment at home. It never fails to keep the kiddos occupied. I must remember to grab more baking soda, vinegar, and dish soap the next time I'm at Costco. The kids quickly ran through the main ingredients and then Hen hit the cupboards for more things to mix in. He collected coffee grounds, flour, cornstarch, salt, and limoncello and the boys set to work. Nearly an hour and a half later, they were finally wanting to move onto something else.
