Enter the book Geek Dad: Awesomely Geeky Projects and Activities for Dads and Kids to Share by Ken Denmead, author of the Geek Dad blog. There was a nice interview with him talking about the book yesterday on Science Friday. It sounds like a lot of fun...among the projects (from Amazon.com).
•Fly a night-time kite ablaze with lights or launch a video camera with balloons
•Construct the "Best Slip n' Slide Ever," a guaranteed thrill ride
•Build a working lamp with LEGO bricks and CDs
•Create a customized comic strip or your own board game
•Transform any room into a spaceship
•Make geeky crafts like cyborg jack-o'-lanterns or Ethernet cuff links
Many of these projects can be down with low cost materials, possibly even stuff you have laying around the house. What better way to spend Father's Day (or any lazy summer weekend) than showing your kids how much fun it is to mess around with science and engineering.You can also check out his Top 10 Dads in Science Fiction and Fantasy while you are there.
