Want to make Halloween truly eerie? Science to the rescue! These ghostly, ghouly hands come alive with just a little help from some simple chemistry. All you need is vinegar, baking soda, glass jars, and rubber gloves. The chemical reaction between the acid and the base turns limp gloves into a spooky demonstration of science in action...expanding the gloves so they come to life! A truly spook-tacular way to invite your Halloween guests to the table!
