At the after dark event last week, the tinkering studio crew was preoccupied by facilitating the love-themed chain reaction in the skylight area of the museum and putting the finishing touches on the star-crossed rat and duck lovers. But we were happily surprised when, as we were putting away the tables at the end of the night, we saw a group of four adults excitedly gathered around a huge marble machine. They had spent about an hour making the complicated contraption and were in the process of filming a flawless run. I captured their creation on (admittedly shaky) iphone video. It’s really fun for us to have the tinkering studio open at these night events and see how much adults can get into the activities when they are given permission to play. Enjoy!
