Keith Ostfeld aka Mr. O, is the director of educational technology and exhibit development for the Children's Museum of Houston. It's probably the best place to take your kids for Halloween since it's an awesome Haunted Museum and while they'll have fun, they'll also learn. Keith tells us about their new app that works throughout the museum, how they're working on the next big thing: teaching kids about building big, public places. As for the Halloween festivities, they include: the Mobile Monster Hunt, a Slime-Off on Oct 27th, a Thriller Dance Party on the 31st. The museum will open late until 8PM on that day.
