The tool i designed is a toothbrush that give the user a toothpaste that is mix with oxygen, water,and toothpaste. My tool use by the user putting the brush in user mouth ,and the user press the red button, give out a oxygen mix to the user teeth. My tool solve the gravity problem in space, that don’t let the space talk the toothpaste all around in space. This tool use for people exploring space only hold a item then two item at the same time because if a person hold a toothbrush and toothpaste it will take space when he or she 2 item them one.
