I carry around my Nalgene bottle everyday; I use it in class and especially at rowing practice. The bottle holds a good amount of water, it’s easy to clean, and the small mouth hole reduces the number of times I spill on myself. The hard plastic is also durable enough to slide against the boat while I’m rowing. The loophole attached to the cap makes the bottle easy to carry, also the cap doesn’t leak at all. The Nalgene bottle was created when the chemist, Emanuel Goldberg, create plastic pipette jars in 1940. These jars were then brought on a camping trip in the 60s, due to the fact that they were lightweight and leak-proof. The “Carry In/Carry Out” trend of the 70s spurred the popularity of the water bottles; the movement urged campers to bring re-usable containers that would not be left in the wilderness.
