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.”
