This is totally unrelated to technology. Someone brought this up so I thought I'd write a paragraph about it. When I was in high school, my buddy Alma had an older Volvo, and we drank more Mountain Dew than water, and we rigged his car up with a cooler in the trunk, and plastic tubes that ran through his trunk into each of the seats in the car, with valves on the end so you could just suck on the tube and get Mountain Dew at will. Turns out it was almost always warm so we didn't use it very long.
We also got a circular tupperware type bin and screwed it into the roof of the car, and had licorice rope wound up inside, with a hold in the side of the container, and a razor blade so you could cut off a section of licorice.
That's it. Fun stuff.
