Science homework

This quarter's science homework was to construct a Rube Goldberg machine which, according to Wikipedia is a "contraption, invention, device, or apparatus", "a deliberately over-engineered or overdone machine that performs a very simple task in a very complex fashion, usually including a chain reaction".

Like the Mousetrap Game or the Honda advert.

Anyway, R and A spent many happy hours in the garage messing with rollers and string and balloons and candle flames. I say "happy..". I suspect that putting those damn dominoes up over and over got a little boring after the forty-seventh time.

But it was impressive!
