However, no mini small ice packs on-drive Ah! Don't worry, young Africans are in China, Huazhong University of science and school of enlighten "bear" design team recently brought a cold bandage and swollen can solve this little problem now!
The band-aid is slightly larger than the 1 dollar coin teardrop-shaped styling, in cotton wool has a raised above the snare drum bag, stored separately in two separate areas of water (H2O) and ammonium nitrate (NH4NO3). Science students see that there are already almost have it now? When used, just put cotton wool on skin wound well, and pressed snare drum kits, water and ammonium nitrate after being pushed through a combination of partitions that produces a chemical reaction for cooling, rapidly in constricts blood vessels to stop bleeding at the same time, provide effect of cold compress to relieve hot gall. Little wound 10 seconds to stop the bleeding. Of course, chemicals are not penetrating the cotton wool will only transfer the feeling of cold. Blood drawn later, shots later, after scratching out ... ... Cold compress bandage small stature very useful ~ miu miu iphone 5
