Dihydrogen monoxide, often shorted to DHMO, is an odorless and colorless compound that is a known component, but not limited to, the following dangers:
- Major component in acid rain
- Death due to accidental inhalation, even in small quantities
- Excessive ingestion produces a number of unpleasant side effects
- Soil erosion
- Corrosion and oxidation of many metals
- Thermal variations in DHMO are a suspected contributor to the El Nino weather effect
- Has been involved in every instance of school violence
The CDC does not identify DHMO as a toxic or carcinogenic substance, but it is well-known that it is a large component of many toxic substances, diseases, and disease-causing agents. These agents can be potentially lethal to humans. The government refuses to ban production and distribution of DHMO because of its importance to the economic health to the nation. 90% of US citizens say that they will sign a petition to ban DHMO.
Now, before you go and sign a petition, I would like to inform you that the formula for DHMO is H2O, more commonly known as water.
This is an example of pseudoscience, fake science, because in this case, water, an essential component to human bodies and the environment, is being passed off as something incredibly dangerous. This is a good example of pseudoscience because although the claims set forth are all true, however the information was rather vague. The information sets forth only negative examples so it is impossible to refute any of the claims. DHMO was only referred to as an alien substance and not being a part of the human body or being a part of the ocean (or being the ocean, really). This grossly misconstrued other people's take on DHMO.
All the scientific claims set forth about DHMO are true to an extent. The scientific ones, such as the fact that it's a major part of acid rain and it contributes to soil erosion, cannot be refuted. However, claiming that DHMO is a major part of school-related violence is stretching the truth a little too far.
People might fall victim to a claim like this because dihydrogen monoxide is not a familiar name for water if you're not a chemistry student. At the time that this hoax became popular, there were many chain letters in emails claiming that other chemicals were dangerous and that people needed to be wary of them. Since there were no positives associated with DHMO, people assumed that it was dangerous and DHMO needed to be banned.
