Some great places to immerse your child in Tech- the San Jose Tech Museum and The Exploratorium in SFO.
Last week was our first time at The Tech and it was surprising to see how quickly kids get engrossed in most of the hands-on projects there. The museum was not terribly crowded and San Jose downtown looked fresh and appealing :) bringing back nostalgic memories of student days there.
Its a great place to see everything in one day and spend time on the projects that interest you most- the IMAX show 'Flight of the butterflies' was spectacular and how cool is it to grow Jelly fish DNA in the wet labs!
