A new app from the publishers of "The Handy Answer Book for Kids" is a great resource for curious kids (and their parents, who — gasp — actually don’t know everything). Why do dogs bark? Why is the sky blue? Why do people have to grow old?
Answers to these and about 800 other questions are now at your fingertips. And it’s also kid-friendly, so you can feel good about letting children explore instead of just turning them loose on Google. There’s also a “surprise me” button to find answers to questions that hadn’t even been asked yet.
