Jack be nimble, Jack be quick,
Jack jumped over the candlestick.
How did young Jack light the wick
Of this glowing candlestick?
Jack said “I can get it done
With a flint made with cerium.
Strike the flint and sparks fly off it,
Because cerium is pyrophoric.
That means it has the property
Of igniting spontaneously.
So to light a candlestick,
Get some cerium, double quick.”
