National Geographic, now weirding out your smartphone

Have a kid who loves odd little factoids about everything and anything? National Geographic has been putting out "Weird But True" compilations in book form for years, but now they're bringing the wackiness to the iPhone, and it's more fun than ever. In addition to all sorts of things you didn't even know you didn't know (follow that?), using the Weird But True app kids can flick between snippets by swiping or shaking, rate items on the weird-o-meter, favorite the best ones, and choose to hear the themed declaration of "That's Weird!" as a variety of voices and accompanying animals agree with what they already knew--this is just plain weird Whether it's the fact that mountain lions can whistle or that the Leaning Tower of Pisa was leaning even before they finished building it, thousands of items make for hours of weird entertainment. Shhh, don't tell them it's educational.   You can download the Weird But True app in the iTunes store for $1.99.
