Sponge Bikini Cleans the Ocean as You Swim

The Sponge Suit is made of an absorbent material that fits inside a 3D printed shell. The fabric absorbs pollutants in the water and seals them away from the skin. It releases the contaminants only when subjected to extreme heat. The designers explain how it works:

This material has multi-model porosity (micro/mezzo/macro porous) that allows it to be a light yet strong absorber with its undulating texture (visible through Electron Microscope). Absorbing everything but water, the material is a powerful tool for water and contaminant separation. The super-porous nature allows the Sponge to absorb in high capacity, up to 25 times of its own weight depending on the density of the substance absorbed. The Sponge does not release the absorbed materials unless it is heated in high temperatures (1,000 degrees Celsius) to re-obtain its original liquid form. This property allows the Sponge to be recyclable as the liquid form is ready to be reshaped having been separated from its contaminants.
