We went to the Maker Faire... the robots were all there...
My kids declared on the way there that "they didn't believe in robots" and had "never seen a real one". I was all ... "but what about our roombas? What about Kevin???" Anyway, Elizabeth grudgingly admitted after the Faire that robots might be real.
We admired many robots. We looked at intricate Lego. We played with technology enhanced pillow fighting pillows (they made cool noises as you waved them around).
The kids' favourite exhibit was the peg board marble run. All three kids were captivated for quite a long time.
My favourite booth was the papas inventeurs. There was the visual indicator of how much time you have before you have to get ready for the bus. There was the rfid enabled music player - kids illustrated their favourite songs on little plastic key fobs and then they could wave them at the lamp to make the music change (there were also fobs to change the lights, because why not?). But my absolute favourite invention was the "don't get off your bum at the dinner table" chair. The special cushion could detect if his kids got up. If they got up, the chair would play countdown music to let them know they had to get back (short grace period). If they didn't, the chair plays "loser" music. If they stayed seated, then it would play "winner" music at the end of dinner.
Afterwards we went and played at the park until supper.
