Katherine Mangu-Ward on the Transparency Grenade

It's usually not a good idea to pull the pin out of a grenade in the middle of a meeting.

Designed to instantly and anonymously publicize what's going on in closed-door meetings or other secret confabs, the hardware-stuffed Transparency Grenade releases a burst of data when activated.
