The Eye Washer 1000 is meant to wash an astronaut’s eye out if something gets stuck in the back of your eye in space or on Mars. There is a tube that connects to the pouch. You will put the tube into the side of your eye. Close your eye and carefully, slowly, squeeze the pouch and water will come into the back of your eye and wash it away. There is a guard for the front of your eye, so water doesn’t get in the front, causing it to spill everywhere. There is also a magnet on the back that will keep the pouch from floating away when not in use.
