For some reason, scientific terms tend to leave many people in awe – even frightened at times. For example, if you were to tell your colleagues that large quantities of dihydrogen monoxide have leaked in the hallway and that inhaling said substance could lead to death, chaos would most likely ensue. Unless somebody actually knows a thing or two about chemistry and calls the facility manager to clean up the water spill ;).

The Chemistry Warning Fridge Magnets allow you to play similar pranks in your own kitchen on non-nerdy guests or flatmates. Each set contains four fridge magnets modelled after actual chemical warning signs and warns against dihydrogen monoxide, chemistry, sodium chloride and atomic nuclei.

But don't worry, these are actually terms for completely harmless things you can find in every single kitchen. Dihydrogen monoxide is another term for water and not actually used by scientists outside of jokes, chemistry happens in your groceries (and basically every other thing), sodium chloride is plain old salt and atomic nuclei are also present in everything in existence.

As you can see, something does not have to be complicated or dangerous just because it appears that way. But your guests don't know that, right? :)
