Fresh (or not so fresh) from swimming through the sewers of science, our charming host--Dwayne, the rat--hurtles into history for more Interpipe Adventures. What’s the Interpipe? We’re glad you asked! Copying how computers have been connected to form the Internet, four mad-scientist-plumbers (Plumb Bob, Phyllis Tanks, P. Liddy, and Portia Potty) linked the world’s sewer lines together to create the Interpipe. Next, the Four P’s created a waterproof device called the iSwirl that can be used to travel back in time with a mere flush of the toilet! Finally, Uncle John found a world-famous puzzle maker to chronicle every Interpipe adventure, and the rest is iFlush history! Here’s how it works: - Every page is packed with the kind of amazing true stories and fantastic factoids readers expect from Uncle John’s Bathroom Readers FOR KIDS ONLY. - Readers use clues in the history-filled stories and factoids to solve puzzles. - Once a puzzle is solved, Dwayne, our ratty host, flushes himself through the Interpipe to take readers to their next historical destination. - The ingenious iSwirl adds a twist by giving readers a choice: solve the puzzle and turn the page, or jump through time to the next historical adventure. “The iFlush lid is open--so jump in for dozens of puzzles, laughs, and weird adventures. I love this book! So much fun, it’s SCARY!” -- R.L. STINE, Goosebumps and Fear Street author “ iFlush: Swimming in Science does for science what iFlush: Hurtling Thru History does for history.
