Guys, it's H2O the molecular model, not H2O the actual water! LOL, now THAT is a doozy!!! *Sighs, shrugs shoulders* To be fair, I'm not the target demo, but if you've got access to the right equipment and a brainy, captive audience, then I predict you'll make a splash with this April Fool's Day prank. Here's looking at you, nerds.
同學們，灑在地上的不是真正的水，而是構成水的H2O水分子模型！哈哈哈，這一招太出彩了！旁邊一堆人聳肩，嘆息。。。不過，我不是這個玩笑的目標人群，如果你手里有合適的材料，又有一群知識淵博的觀眾，這個點子肯定能在愚人節大放異彩。哈哈，看你們的了。
