Hey, diddle, diddle,
The cat and the fiddle,

The cow jumped over the moon;

The little dog laughed to see such sport,

And the dish ran away with the spoon.

Work as a team to design and build a unique invention that completes a chain reaction inspired by the nursery rhyme Hey Diddle, Diddle.  Have fun finding ways to include elements such as a cat playing the fiddle, a cow jumping over the moon, a laughing dog and dish running away with a spoon somewhere in the working part of the chain reaction.  Then showcase your invention at the New Hampshire Farm and Forest Expo in May or at the Young Inventors Invention Convention at UNH in March.

The Rules

Teams of two to eight youth, ages 8-18 can form teams to build chain reactions.  Teams will be awarded points for the number of successful unique steps their machine completes and should record their progress in a journal and consider things that were learned during the build.
