When I thought about what design to enter for the Mars Medical Challenge, I saw on Wikipedia, that when the astronauts are in space traveling to mars, their bones get brittle and weak. I thought that I could create a medicine pouch that has a twist-able lid and when you twist the cap left it pops open a seal inside which makes it easier for them to drink the medicine and when you turn the cap to the right it seals it up again. This creation will be useful because, during their travels and stay in space, they can receive a vitamin dosage from the pouches daily. They could also use this to fill with pain meds to take on their discovery missions, in the chance they get hurt. Also the twist-able cap helps so that the cap will not float away when they are in space.
