The Keepable Cap by Adam Robinson is a new innovation that strives to make your plain, ordinary tap water way more delicious. Rather then using and disposing of store-bought water bottles, this device aims to use what you already have in your house.

Inside the Keepable Cap is your choice of flavors, vitamins, or even energy-producing stimulants. Simply refill your favorite bottle, screw on one of these caps and save the environment while quenching your thirst.
