English
By (author): Mary Batten
The title says it all. Its yucky. Its gooey, It makes your food chewy, Ptooey! Ptooey! Oh, spit. Ew! Nasty! Ew! Gross! But spit is no spitball joke. Drool is cool! Its one of the most amazing fluids in your body. In Spit, renowned science writer and childrens author Mary Batten examines everything thats cool about drool. Spit keeps your mouth moist. It begins digesting food the minute you take a bite. It keeps your teeth from wearing away. It keeps your tongue from choking you to death! But it isnt just humans that rely on spit, anything with a mouth needs saliva to keep functioning. A bat has special saliva that stops its victims blood from clotting. A spitting spider can trap prey in gooey saliva that it can spit in 1/700th of a second thats fast! And, if spitballs are your thing, perhaps try your hand at spitting antelope dung; the record in South Africa is 51 feet! In Spit, Battens informative and informal text is paired with humorous illustrations and real-life photos to help tell the important story hiding in this gross-out subject. From the DNA in human mouths to the science behind Pavlovs dogs to the astounding wonders of saliva in the animal kingdom, Spit uncovers the secrets secreting in the many mouths on the globe.
