A Swedish man, Mats Nilsson, was listening to his grandfather when he was telling stories. His grandfather told him how he was drinking cider at work in a shipyard as a welder. They often spilled a little on their clothes and it dried. When they then started working again, the dried cider protected their clothes from flames or sparks.

Now he has made a 100% biological safe fire protection called Apyrum. Main ingredients are vinegar (CH3COOH) and citric acid (C6H8O7). There are two drawbacks: one is that the material you want to protect has to be porous. Like curtains, fabrics, upholstery, furniture foam and paper. The other drawback is that if you wash your curtains, you have to protect them again as Apyrum dissolve in water. However, consider the dangerous chemicals in other types of fire protection, I would go for it.

I saw a program on Norwegian TV (link below),  last autumn where this was demonstrated, and I got completely fascinated. It was very impressive. However, it took me some time to find back to where I had seen this demonstration and write about it in my blog. You can see a video of this program on the page above. Børge Jomaas, borge,jomaas at nrk.no is the journalist that made that part of the program.
