Scientists from Singapore and the US have developed a gel that can remove contaminates from water, making it clean and drinkable.

They began to work on the purifier in the wake of the 2004 Indian Ocean tsunami.

After it, like many disasters, survivors lacked access to clean water. They also had no power.

Among the most common ways of purifying water is to boil it, but when there’s no viable heat source clearly that becomes impossible.

The researchers developed an absorbent pellet that cleans what it takes in, making the liquid squeezed out of it safe to drink.

What makes it work is a combination of silver nanoparticles and a specially formulated polymer.

Silver rids the water of harmful parasites and bacteria while the plastic, in addition to lending an absorbent quality, keeps the silver contained.

4 grams can clean up to a half a liter of water and be used up to 20 times.

The manufacturing cost is estimated at 50 cents per disc.

Also, as it’s lightweight it could be easily transported and even airdropped into areas needing it.
