Publisher's Synopsis
For fans of Jon Scieszka's "Frank Einstein" and Bob Pflugfelder's "Nick and Tesla" series. 10-year-old Theo's crazy grandma and genius little brother have been experimenting! There's a rocket-shaped hole in the dining room, mint green slime oozing out the dog door, and a secret worm garden in the upstairs hall closet. And why exactly is Grandma looking for the baking soda? Fifth grade is complicated enough without Grandma and Toby blowing things up. There's a cute girl he wants to impress and a bully picking on his best friend, the science test he should be studying for, and his mom might be bringing octopus popsicles to the School FunFest. Can Theo juggle all the balls in the air, or will they land-splat!-like one of Toby's raw egg catapult experiments? Includes science and cooking experiments for kids ages 8 and up!
