Everybody knows about playing with dominoes, but what you may not know is that a domino can knock over another domino which is about 1.5 times larger. So what I have here is a chain of dominoes. Each one is 1.5 times larger than the previous one. And the smallest domino is about five millimeters high and one millimeter thick. And I'll carefully place it.
大家都知道怎麼玩骨牌，但你可能不知道的事是，一張骨牌可以撞倒另一張比它大約 1.5 倍的骨牌。我這擺的是一列骨牌。每一張都比前一張大 1.5 倍。最小的那張骨牌大約是 5 毫米高然後1 毫米厚。我會小心地把它擺好。
And there are 13 dominoes. And the largest domino—it weighs about a hundred pounds, and it's more than a meter tall. Ready?
有 13 張骨牌。而最大那張骨牌－－它約重達一百磅(約 45 公斤)，且高度超過一公尺。準備好了嗎？
Boom! That was 13 dominoes. If I had 29 dominoes, the last domino would be as tall as the Empire State Building.
碰!那樣是 13 張骨牌。如果我有 29 張骨牌，最後那張骨牌會和帝國大廈一樣高。
