These cups wouldn’t be my first choice for hiking, camping, survival or for my bug-out-bag, but I will be making some for backup. These awesome little cups fold down flat and if you make some in different sizes, you can stack them inside each other.
Providing you use a good quality duct tape, these cups are water tight and they don’t give off any taste or taint. Water just tastes like water! They will break down and possible taint the water if you use them for hot drinks, so this is a no, no… These duct tape cups are easy to make, light weight, functional and they cost next to nothing.
