Another nearby robot would re-arrange wooden letter blocks until you asked it to spell your name, when it would kindly oblige.
Around the top floor, they also had some nice exhibits on digital logic and programming microchips (we are in Silicon Valley after all). These consisted of a Mr. Potato Head whose clear head showed off his microchip brain, in a room with lights, fans, thermometers, etc. that you could control. By placing labeled blocks in slots you created a logic chain that would cause Mr. Potato Head to perform some action. For instance, the chain could read "Light is on" "and" "Mr. Potato Head is hot" then "Speak". You then sent these commands to the PIC brain, and he would execute them if the conditions were right. So if the light was on and the fan was off, the temperature would rise, and Mr. Potato Head would start talking.
They also had nice DNA exhibit, the best part of which was a functioning wet lab. Of course, I had to test it out. I was quite impressed, they had the ingredients (e. coli? and gfp? plasmids) nicely laid out, a how-to video which you followed at your own pace, and included the proper safety procedures; goggles and gloves. They walked you through the entire process of getting the bacteria to uptake the genes by heat-shocking them. Since the bacteria need some time to grow, you incubate overnight and then can check back on them via their on-line interface.

Also on the lower level was an awesome demonstration of NASA's Extravehicular Mobility Unit (powered space suit). A chair had several compressed air jets to levitate it, and then a few more for control. Excluding the minor friction I noticed (which may have had something to do with the fact that I'm about a hundred more pounds heavier than their target 7 year old), it was a good demonstration of what the astronauts have to deal with to maneuver in space.

Overall this was a fantastic museum: I was only able to spend a couple of hours here, but one could easily loose a day or two in these very interactive halls.
