Claudia Donovan's Goo-Nade is a tool created by Claudia Donovan while she was an agent.
This "Claudia Donovan Original" was invented by the Warehouse 13 agent Claudia Donovan. It's used by many agents to quickly neutralize several artifacts at the same time.
It was used by Artie to neutralize a cluster of artifacts that had activated simultaneously as a result of the misplacement of the Norge Porthole.
This device is designed like a regular smoke grenade, but tape covered in camo masking the case. Also, when it goes off it releases a cloud of vaporized neutrailizing goo.
