Ok, I made the best thing you could ever carry, they are called A.W.C.(Artificial Wormhole Carrier). What it is is that it can carry any item of any size with ease. The best part is it has unlimited space. You can carry food, water, weapons, anything. There is couple things that has couple down sides. Like if you leave a live grenade in there...there is the possibility that it could create a black hole that could swallow the entire city....
