Adventures in Science

Today Christine, the Dash Man, Ben and I headed off to the Ontario Science Centre for Adventures in Science (cue Dr.Who-type music).

Above you'll Christine suiting up for her first ever space walk - all was well until she ran into some slimy green dudes demanding to see her leader - she quickly pointed to her Dad.Here's the Dash Man hanging out in the little kids area putting lots of public toys in his mouth - hmmmm...germalicious.
Here Christine decided to try out her xylophone skills - love that spout medley!
Here's Dash trying to figure out what wire to cut to deactivate the bomb (aka wire toy thing). Cut the blue one! Not the green one! Nooooooooooooo!
Footnote: cutting the green wire resulted in the Spit-Up function being set off accidentally as well as the toy bomb.
And finally - any guesses on what this is?
