Korean scientist Jeabyun Yeon has invented a new type of scuba mask which allows you to breath under water without the use of an oxygen tank. The Triton Oxygen Respirator uses a new type of artificial gill technology which extracts oxygen from the water through a filter and allows humans to breathe under water for a long length of time. You simply bite down on the mask and do not need to perfect the skill of breathing in and out while biting the existing respirators, which can take some getting used to. We can now breathe under water like fish!
