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

Jan 17, 2015
SciShow host Michael Aranda explains what is actually inside those small white packages marked "Do Not Eat". Inside those packets are desiccant silica gel balls that absorb moisture that could otherwise damage the product. Silica Gel can adsorb substantial amounts of water.

Since the mid-20th-century, Silica Gel has been widely used as a desiccant and placed inside containers to prevent the contents from getting damp. Most commonly, it comes in the shape of beads wrapped in a permeable packet and is used in everything from museum display cases to electronic equipment packaging to boxes of seaweed.
