With the Hoe dinge werk series every young do-it-yourself scientist can do fun (sometimes explosive) experiments in the backyard! Make a bouncy egg, grow bacteria, keep fruit fresh, blow up a balloon using yeast . . . If you’re curious about things like fungus and enzymes or want to see how your lungs and digestive system work, you’re in the right place! The book also includes a quiz to test your knowledge!
