奇妙的箭头
奇妙有趣的箭头，
开始两面向上的箭头的魔术板，
瞬间能变成两个向下的箭头，
而后瞬间又变成了侧向的箭头，
最神奇的是最后魔术师竟然变出多个不同的箭头。
零手法，超强效果。

Wonderful Arrow
The arrow on the square shaped card points in the same direction, Front to back. As the performer continues to turn the card the arrow begins to point to varying directions.
As a grand finale, the card is shown on the back again and it is shown to have changed to have multiple arrows on the back of the sign.
