A party trick when the wine is flowing.

HOW TO DO THE TRICK

Explain that just as a glass prism splits up the different colors of white light, when different colored light passes through glass, it is also affected to an extent that depends on its color.

Write the words CARBON DIOXIDE on a piece of paper, CARBON in red and DIOXIDE in blue. Put the paper close behind the stem of a wine glass, and look at the words through the stem. The red letters turn upside down, but the blue ones don't.

So is the glass affecting the red light more than the blue?

聚會上的小把戲

說明：首先要解釋一番，就如白光通過三棱鏡會分離出不同顏色一樣，帶顏色的光透過玻璃也會這樣1n%l8K,OKg。接著在一張白紙上寫上“CARBON DIOXIDE”“CARBON”用紅色寫，“DIOXIDE”用藍色寫)!#)Y*2UKNc|。透過高腳杯的杯子干看這兩個單詞，會發現“CARBON”倒過來了，而“DIOXIDE”卻沒有，所以，紅色的光更容易受到玻璃的影響，對嗎？

A good trick to try on a group of drunken scientists.

事實上，這個把戲的關鍵就在于，紅色的也好藍色的也罷，穿透玻璃的還是白光，而不是帶有顏色的光，不過這個小把戲倒是可以騙騙喝多了的科學家們[&R3voUFGouRN。uc3;dYCHu|&YdCs9^UTJ2#18fXHjUqjhtS.llOOR 來源:可可英語 http://www.ccdyzl.cn/read/201112/165154.shtml
