For two years, Tinker developed science theatre performances for Nemo in Amsterdam, called Technology Lives. Under the supervision of Professor On/Off, children built a robot. And once they were past the age for Bob the Builder, they would be ready for Virgil Spatkraker, the sturdy captain recycling his proud ship into a cosy house for landlubbers.

And then there was the Secret of the Bubble. Children seem to be the only ones who remember that chemistry is rooted in alchemy. And so they got to help Leonardo Bubble trapping his thoughts into soap bubbles. Tinker wrote the script, directed the show and managed the whole caboodle.
