At least one April Fool's joke has gone far enough for the authorities to come out with a clarification. This time involving an old April Fool's hoax posted on the Wake Up, Singapore Facebook page regarding Dihydrogen Monoxide - commonly known as water.

According to Wikipedia, "the dihydrogen monoxide hoax involves calling water by the unfamiliar chemical name "dihydrogen monoxide" (DHMO), and listing some of water's effects in an alarming manner, such as the fact that it accelerates corrosion and can cause severe burns. The hoax often calls for dihydrogen monoxide to be regulated, labeled as hazardous, or banned. It illustrates how the lack of scientific literacy and an exaggerated analysis can lead to misplaced fears."

The Public Utilities Board via their Facebook page announced that a " post from Wake Up, Singapore’s Facebook page is a hoax/April’s fool joke. Dihydrogen Monoxide (DMHO) is water.

PUB would like to remind the public that they should not post or spread such misleading information."
