Spit
Spit
The title says it all.
It's yucky. It's gooey It makes your food chewy Ptooey Ptooey Oh, spit.
Ew Nasty Ew Gross But spit is no spitball joke. Drool is cool It's one of the most amazing fluids in your body.
In Spit, renowned science writer and children's author Mary Batten examines everything that's 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 isn't just humans that rely on spit, anything with a mouth needs saliva to keep functioning. A vampire bat has special saliva that stops its victim's blood from clotting. A spitting spider can trap prey in gooey saliva that it can spit in 1/700th of a second -- that's fast And, if spitballs are your thing, perhaps try your hand at spitting antelope dung; the record, set in South Africa, is 51 feet
In Spit, Batten's 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 Pavlov's dogs to the astounding wonders of saliva in the animal kingdom, Spit uncovers the secrets secreting in the many mouths on the globe.
