So I went to GNC after I read an article about saving a planet by not using so much plastic bottle and found this! The name is Bobble, LOL, pretty cute name ;). It's pretty much a reusable self-filtering bottle. I think it's a genious idea where you can keep on using the same bottle, intead of buying a new one water each time. It's eco-friendly which helps us saving our planet! I go to gym every day and with this, I dont have to line up at the water cooler section or even buy a new water bottle anymore. I just use tap water, fill it and go! I think the price is like $9+. You guys should try it! It's awesome!
