Although the packets are labeled “silica gel,” they aren’t guaranteed to contain nothing but silica gel. In fact, they can contain cobalt chloride or other poisonous things. If you do one day want to eat silica gel, I would recommend getting it from a food- or laboratory-grade source rather than from a packet which says “DO NOT EAT.”
