Ark bomb

"The ark is in fact a Goa'uld explosive device."

- Teal'c.

The Goa'uld ark was an explosive weapon created by the Goa'uld.

Overview
The ark was a small coffin shaped device with an image of an Eygptian eye on its surface with scarabs on the corners. Once the image was rotated, the internal bomb was capable of being send which resembled a circular shaped device with Goa'uld writing on the sides indicating the time. The centre contained a light greenish glass dome.

The sides of the ark contained slots through which a user was capable of accessing the internal control crystals. However, the improper use of the crystals was capable of either increasing the time til detonation by tampering with the red control crystal or halting it or bring about a premature detonation. Scans can reveal that the device contains a ten pound block of Naquadah.

It was incapable of being moved as it possessed sensors capable of detecting an attempt to relocate it which can result in it exploding. Furthermore, the removal of the power regulation crystal from the control board, it can result in the ark exploding as well. The inputting of the proper access code was, however, capable of deactivating the bomb.

History
Sekhmet held one such device during her time on Earth before she was placed in a Stasis jar. It along with several other artifacts were recovered by Napolean and later by the Nazi's. During this time, it eventually made its way to the rogue branch of the NID.

It was activated by the genetic personality of Sekhmet that resided in the girl Anna and was going to detonate in sixteen hours. SG-1 attempted to deactivate the Ark as it threatened to devastate a city on Earth at the time. Bill Lee was finally able to stop the ark from exploding by using Anna's drawings to input the deactivation code.
