The mere sight of it was all it took.
Do you remember this game? A highlight from my childhood (and my husband's too, as I recently discovered) involving a fascinating contraption: you turn a crank which rotates a set of gears, causing a lever to push the stop sign which hits the boot, kicking the bucket, spilling a marble down a flight of stairs and into a pipe, hitting a rod, causing the hand at the top of the rod to tip another marble into a bathtub. (Insert breath here.) The marble spirals down the bathtub drain onto a diving board, catapulting the diver through the air into a bucket, causing a cage to fall down, trapping the mouse underneath.
Too, too fun. Clever and bizarre. It's been keeping us busy after dinner around here. :)
