Kate Biberdorf - Kate the chemist : the big book of experiments

Hi! My name is Dr. Kate Biberdorf , but most people call me Kate the Chemist. You can usually find me teaching classes in Austin, Texas, or setting off explosions on national TV. For years, Ive been bombarded with requests for at-home activities; so over summer break, I embarked on a mission to compile my favorite science experiments into one awesome book!

Do you know what chemistry is, besides being the best science in the entire world? Its the study of energy and matter, and their interactions with each other. Like how a gecko climbs a wall or how a rocket moves through space. If you follow the protocols (i.e., recipes) in this book closely, you will learn how both of these things happen. Ill even show you how to use unicorn glue and send a secret message to your BFF!

Every experiment can be done safely in your home with materials purchased online or in local pharmacies, craft stores, or home improvement stores. Just pay close attention to the safety icons and messiness levels to avoid hurting yourself (or your moms favorite table).

Lastly, these experiments are better when shared with friends. So what are you waiting for? Call your bestie, grab your gogglesits time for science!

A Note from Kate: I did this experiment the first time I was on a TV show where I had to follow a script and couldnt just say whatever came into my head. I was so nervous about making mistakes, but I ended up having one of the best days of my life. On the very first take, the rubber band snapped and I accidentally poured colorful soap bubbles all over the main actors head. Ah!!
