People with great ideas, some famous and some not so much, invented the things we use everyday. Inventors like Ben Franklin, the Wright Brothers, Heddy Lamar, and Josephine Cochran dreamed the big dreams that led to the lightning rods, airplanes, torpedoes and dishwashers.

There's a monster out there. It's huge, powerful, and it's been around forever. It can destroy a human being in hundreds of different ways. It's energy! Energy can make some very interesting things happen, and it's stored up all around us. It's in the tiny sea creatures that died hundreds of millions of years ago and eventually became oil. It's in the guillotine that slides down and chops your head off. And you'll need lots of energy if you plan to fire your teacher from a cannon.

Gazelle-gnawing lions! Chum-chomping sharks! Man-mashing elephants! The world is filled with angry animals. But which ones really pose a threat to humans?

Predators are natural to every environment-and only the quickest and cleverest prey can avoid becoming meals. So while a banana-munching monkey might escape the razor-sharp claws of a stalking tiger, a fat cow wading into a piranha-infested river is sure to become lunch.

Science doesn't have to be all about boring lab reports and tiresome test tube measurements'it can be fun, explosive, and really gross. Just think about the old alchemists who tried to turn urine into gold or the acids that can burn flesh right off the bone. Not to mention dangerous metal elements, fiery reactions, and gasses that could make anyone gag. But there are safer ways to experiment with the more horrible aspects of science, and all the necessary ingredients can be collected throughout your home- under proper parental supervision, of course.

Follow Oddblob the alien on his out of this world tour and you'll be an expert on everything galactic in no time. Oddblob will tell you why you can't be in outer space without a space suit (you'll explode!), why you definitely don't want to stay in the Neutron Star Hotel, and why you'd better bring both your sunscreen and your mittens if you plan on visiting Mercury.

Repulsive regurgitations, icky intestines, boisterous bowels, loathsome livers, attacking acids-all of these are involved in the foul science of digestion. Can you stomach it? If not, keep a barf bucket handy! After eating your breakfast, lunch, dinner or midnight snack, you probably don't think much about that food until you visit the bathroom several hours later. But in the meantime, the edibles you gobbled up take an amazing journey-a trip through the fizzy digestive tract that's also really, really gross.
