The Scenario
It is easy to forget that access to potable water is considered a luxury for most of the world. You are reminded of this fact on a trip to a rural village in East Asia. You learn from the locals that their water supply has been contaminated--the cause of recent illnesses that sound a lot like cholera and dysentary. In addition to dirt, sewage, bacteria and parasites, you suspect other contaminants such as arsenic and benzene from industrial dumping many miles upriver. Ideally, nobody should drink this water--but the villagers are unwilling to relocate.
The Challenge
Create a makeshift solution to filter and purify the water. The solution should be permanent and able to provide drinkable water for 20 to 30 people. Tool and materials at your disposal include materials that can be reasonably extracted from the environment and items on the supply list. You have 48 hours.
Supply List
- 2 barrels
- 1 bicycle with flat tires
- 1 car battery
- 6 1-liter plastic bottles of water
- Various lengths of bamboo tubes (1" to 3" diameter)
- Variety of tools (saw, hammer, pliers, hand drill)
- Steel wool
- Endless supply of coconuts
- $10 in mixed American coins
Send a detailed description of your MakeShift solution with sketches and/or photos to makeshift@makezine.com by July 1. If duplicate solutions are submitted, the winner will be determined by the quality of the explanation and presentation. The most plausible and creative solutions will each win a MAKE T-shirt. Think positive and include your shirt size and contact information with your description. Good luck!

MakeShift 02: Analysis, Commentary, and Winners
Tragically, the MakeShift 02 challenge is all too plausible: the United Nations estimates that approximately 1.1 billion people in the world are forced to drink from unsafe water sources. That is what this MakeShift challenge is about: applying creativity to solve an important global problem, and educating others as to how it can be done.
Thanks to all the MAKE readers who took on this very difficult and important
challenge. Here's an analysis of several proposed solutions, and the winning entries for Makeshift 02.

MakeShift 02: Mark Kissler's "Eichhorina Crassipes" Honorable Mention
Mark Kissler's entry showed great analysis, approach, design, and presentation. The addition of the water hyacinth virtually eliminates the need for activated charcoal, which makes this approach robust.

Hey Make,
what's the deal?
The first month's solution was revealed before the second issue?
Have you gotten any submissions?
I for one am itching to know what you chose as this month's winner.
Thanks

Well First you need the hand drill, then you take 1 of the "endless" supply of coconuts, and drill 2 holes into the coconut. Drink from one whole of the coconut and place the other whole facing the sky and drink!
