Rube's Gold Ribbon

 refers to an unmarked quest in Fallout 3.

Gold Ribbon Grocers is a store on Jury St, near Jury Street Metro Station, west of Megaton.

The entire store appears to have been set up as a Rube Goldberg machine, using pressure plates, a long row of boxes, several traps and explosions. Your reward for setting off the Machine is a few missiles, a mininuke, Nikola Tesla and You and Tumblers Today. For this reason we suggest not grabbing the many boxes of Sugar Bombs and Abraxo Cleaner until after the Machine has completed.

Setup
Follow the arrows to a...
 * Pressure plate triggering log-with-skull
 * ...triggering a long line of boxes
 * ...triggering a Pressure Plate
 * ...triggering a Pitching Machine
 * ...that eventually pushes down a fire extinguisher on a Bear Trap
 * ...which explosion makes a Grenade Bouquet fall down and explode
 * ...setting fire to the gas cloud, which will seek its way to the second floor
 * ...shaking a kid's slider (!) to drop its contents down the hole!

Activating the mechanism after "destroying" the setup

 * If you went ahead and disarmed all the traps before picking up your missile and reading material, you can simulate the explosion simply by shooting the gas cylinder lying next to the bear trap - you might want to stand back though. Following the ensuing explosion the books and missile will fall out of the hole in the roof on the other side of the room.
 * Another alternative is to shoot the end of the slide with a reasonably high-impact weapon, such as a hunting rifle. This seems to work in cases where the items -almost- make it down the slide.
 * Alternately, you can gain the reward by igniting the gas cloud (for instance by shooting the generator until it explodes) in the back.
 * If all else fails, the slide can activated with a Frag Grenade.

Reward

 * Nikola Tesla and You
 * Tumblers Today
 * 3 Missiles
 * Mini-Nuke
