"Gurgle, burp, ooze, and squirt--sometimes our bodies do the most disgusting things! Our bodies are food-processing factories that produce oils and gases and waste. From making sticky earwax and stinky sweat to letting out loud burps and embarrassing farts, this entertaining book describes why our bodies do the rude and hilarious things they do. Get your hands dirty, too, with some easy (and painless!) experiments."--Provided by publisher.
