front cover



When a Love of Science Meets a Love of Awesome, Ordinary Objects become Extraordinary Experiments. Learn to…


• Amaze onlookers as your head inflates to twice its size
• Pierce a balloon without popping it
• Power a mini-rocket car with Coke and Mentos
• Cause a metal can to crush itself

• Blow out a candle 25 feet away with a giant air vortex cannon

However old you are, it’s time to be the coolest kid on the block.



Science yields some pretty cool stuff. What’s even cooler is pulling off some of the most awesome science experiments of all time—in your own home. Using ordinary, household objects and clear, illustrated instructions, Stephen Voltz and Fritz Grobe (the brilliant mad scientists behind the Coke and Mentos geyser phenomenon) make 25 epic experiment extravaganzas accessible to cool-stuff connoisseurs of all levels.


Then they add one more thing: science. Each experiment includes a careful explanation of the science that makes it work, thoroughly breaking down the principles in a way that will inspire a love of scientific experimentation and take you from amateur to genius level in no time. You’ll construct a paper plane that flies forever, make Coke and Mentos fountains of Bellagio proportions, and, yes, build a hovercraft.


And you’ll do it all on your own, eventually gaining enough expertise to figure out your own variations and new experiments. With an appetite for really, really cool stuff, and knowledge of the science behind it, nothing can stop you from making the world your science lab and transforming the objects around you into impressive scientific productions.


Put on your safety goggles and get started.




STEPHEN VOLTZ and FRITZ GROBE are the founders of EepyBird. In the EepyBird Laboratory in Maine, they experiment with Coke and Mentos, sticky notes, paper airplanes, ping pong balls, and more, searching for ways to transform these things from everyday life into something new and unforgettable.


In 2006, they started an Internet phenomenon with the release of the viral video classic, “The Extreme Diet Coke and Mentos Experiments.”


Since then, they’ve taken their crazy science experiments to The Late Show With David Letterman, Ellen, The Today Show, and Mythbusters, as well as live events in Las Vegas, New York, London, Paris, and Istanbul.


EepyBird has received four Webby Awards, two Emmy nominations, and their videos have now been seen over 150 million times.
