This is a lamp with a touch sensitive on/off/dimmer switch, in which the all metal body of a 5 liter mini keg acts as the switch.

I'm not the originator of the project, just cooler than my friend who chose not to make an instructable for his lamp.

Not including the keg itself, which will vary by beer type and location, all the other parts cost less than $20.00.

Note:
This project involves modifying an electrical plug which could potentially be dangerous or a fire hazard. I'm not responsible for any damage caused by you following this instructable.

Step 1: Parts

All the parts can easily be found in the electrical isles of your local Home Depot.

Parts:
- Mini Keg
- Touch Dimmer (screw-in type)
- Light Socket
- Light Bulbs
- Plug / Extension Cord
- Electrical Tape
- Aluminum Foil

Tools:
- Needle Nose Pliers
- Utility Knife

Step 2: Prepare the Keg

Drink the Keg.

You will need to remove the tap and air vent in order to fit the wire through the inside of the keg.

I don't have pictures of the process, but just pull the tap all the way out until it comes completely out of the keg and then use pliers to pull out the rubber stopper. Do the same thing with the air vent plug and rubber stopper.

You might also want to wash out the keg to get rid of the stale beer aroma.

Step 3: Wiring It Up

This step goes over the wiring of the plug through the keg and attaching it to the light socket.

My Home Depot was out of just plugs attached to a wire, so I ended up having to buy this extension cord. It cost a grand sum of $1.24. The light socket I chose to get does not have a switch, if it is plugged in it is on. I chose one like this because the touch dimmer switch acts as an on/off switch as well.

1. Cut off the female end of the extension cord.
2. Thread the wire through the two holes in the keg.
3. Strip the ends of the extension cord wire and the light socket.
4. Splice them together and cover with electrical tape.
5. Pull everything back through the keg.
6. Test fit.

Step 4: Adding the Touch Switch

As you can see, the touch switch has a metal contact on each of the tabs that stick out from the bottom. Because the light socket I got is plastic I had to extend the contact points with aluminum foil to get them to reach the keg. If you don't do this, the dimmer switch won't work.

1. Fold up a 2" by 12" piece of aluminum foil until it is about the height of the light socket.
2. Repeat.
3. Push the foil between the contact points on the dimmer switch and the light fixture, making sure that the foil is long enough to touch the keg.
4. Tape the foil into place for sturdiness and appearance.

Step 5: Enjoy Your New Lamp

1. Add a light bulb and plug into the wall.
2. Touch lamp.
3. Enjoy not sitting in the dark.

You may have noticed that there is no step on how to attach the light socket to the keg. For my purposes I decided that I don't need a lamp shade, and so there is no additional weight on the light socket assembly. The assembly is stable enough on the top of the keg for my purposes thanks to the wires and foil holding it in place. If I had a glue gun or epoxy I would most definitely attach the lamp more permanently, however for now I don't need too.
