Manel Torres has developed Fabrican, a cotton-fabric that comes in a can. Once sprayed onto your body, the pressurised liquid turns instantly into a fabric.
Each squirt from the can sends thousands of cotton fibers splattering against your skin. The fibers then bend together to form a disposable garment that peels away when you undress. Since the fibres are delivered in a diffused form, other elements can easily be added, like perfumes, pigments or treatments.
The web of cloth is obviously quite thin but if you spray more lavishly you can get a rather dense fabric.
