In the slums of the Philippines, there are 8,000 house fires every year. Many of these fires rapidly escalate into infernos that threaten property and families in communities comprised of tightly packed wooden and plastic dwellings. Yet at a cost of around $45, a simple fire extinguisher is out reach financially for most who live in these communities.

City administrators in Las Piñas worried about 600,000 residents who live in these conditions. To address this issue, the city team up with the design agency DM9 JaymeSyfu to come up with an inexpensive way that homeowners could protect themselves from fire. The result is a $1 fire extinguisher that can easily put out small fires on the spot - reducing the chances that the fire will blaze out of control.

How does it work?

The design was inspired by a typical kid's science experiment — combine vinegar with baking soda and you get a foamy stream of liquid. This is what is makes those erupting volcanoes you see at the elementary school science fair. The developers found that by combining these two ingredients at just the right moment, the resulting carbon dioxide that is released in that foamy mix could be used to smother the flames of a small fire.

The pocket fire extinguisher was invented to help people in the poorest communities, but with its low cost and portability, the design company expects it to become popular alternative to the traditional bulky and expensive fire extinguisher.
