A song. A few new discoveries.

Follow body-based units, cubits, hands and fathoms into the story of meters and modern standards. When everyone uses the same unit, the treasure map finally makes sense. Historical unit origins varied; the modern inch is exactly 2.54 centimeters.

Made for curious kids around ages 6–12 and the grown-ups watching with them. Music and animation created with AI tools under Mike Sego’s direction. YouTube’s video description includes the release notes and credits.

Smarty Party! Big foot! Little foot! The treasure clue said, "Twenty feet from the tree!" So we stepped it heel to toe: one, two, three... We both grabbed a shovel and we started to dig, But one of us had little feet, and one of us had big! Two holes, two places, and no treasure at all, 'Cause whose foot is a foot? Is it big? Is it small? Big foot! Little foot! Stomp! Stomp! Stomp! Long arm! Short arm! Clap! Clap! Clap! Everybody's body is a different size, Measure with your body and you'll never find the prize! One measure for the world, one measure for all, The same for the big and the same for the small! Elbow to your fingertip: a cubit, nice and long, Egypt built the pyramids with cubits, big and strong! Put your hand out flat: four inches is a "hand," Horses still get measured that way all across the land! Stretch your arms out wide: a fathom, fingertip to tip, Sailors checked how deep the sea was, underneath the ship! But my arm's not your arm, and your hand's not mine, Every body's different, every single time! Big foot! Little foot! Stomp! Stomp! Stomp! Long arm! Short arm! Clap! Clap! Clap! Everybody's body is a different size, Measure with your body and you'll never find the prize! One measure for the world, one measure for all, The same for the big and the same for the small! Hey! Every town and every kingdom had a foot of its own, And a pound was a different pound in every single town! A pound of candy here, a pound of candy there, One bag's bigger than the other! Hey, that's not fair! Builders argued, sellers argued, everybody yelled, "Whose?!" The world needed one measure everyone could use! Seventeen ninety-one: France makes a plan, A meter from the Earth, not the foot of a man! Eighteen seventy-five: seventeen countries say, "Let's share one meter and one kilogram!" Hooray! Nineteen fifty-nine: the inch gets pinned down, Two point five four centimeters in every town! Nineteen eighty-three: the meter's measured by light, Exactly the same everywhere, day and night! Big foot! Little foot! Stomp! Stomp! Stomp! Long arm! Short arm! Clap! Clap! Clap! Everybody's body is a different size, Measure with your body and you'll never find the prize! One measure for the world, one measure for all, The same for the big and the same for the small! One measure for the world, one measure for all, The same for the big and the same for the small! Same tape. Twenty feet. X marks the spot! Dig, dig, dig... Treasure! Smarty Party Songs! Like, subscribe, PARTY!
