Why You Shouldn't Eat Those Packets That Say 'Do Not Eat'

In plenty of packages that need to stay good and dry — including some types of dried food — you'll find little packages that say "do not eat." This is why you should definitely follow that advice.

Inside those packs typically lurks silica gel, which sucks up moisture by adsorption — where water adheres to the surface of the material. In fact, a single grain can suck up 40 per cent of its own weight in H20. And that's why you shouldn't eat it: while it won't kill you, it will suck up pretty much all of the moisture in your mouth and — if you get that far — throat. Which, SciShow claims, would make the Cinnamon Challenge look like a walk in the park. Gulp. [SciShow]
