one of Nana and Gpa's presents. This book looks awesome. Its got experiments and crazy things to do with your kids that might be dangerous and that you might not normally let your kids do with all the instructions and places to write notes. It even has all the cautions like may cause upset stomach or may make a mess. So cool. It has things like licking a batterie (I totally remember doing that) microwave explosions and cooking in the dish washer. Were going to have fun with this book. Don't get me wrong i am a little nervous but it will be fun.
