Reddit reviews ReNext 10 Pcs 5ml Empty Eye Dropper Bottle Plastic Eye Liquid Screw Cap Lids

Tooth powder plus 5 mL dropper bottle has been my go-to for years. Bonus: it's simply various carbonates (aka limestone) and menthol, so I don't feel bad spitting it into a shallow hole.

So, first: Hike your own hike. That applies to a lot of things, including gear. If you're looking for the "best" of any item, you can ask 10 hikers and get 10 different answers.

That said, there's one thing I swear by: bleach. Forget all those other purifying contraptions and gimmicky ways to quench your thirst. A small eye dropper of bleach will last a lot of miles, it will almost certainly cut your pack weight and possibly even be easier and quicker than your current method of making water. And, to top it off, bleach is inexpensive and widely available in stores.

How it works:

• Use plain bleach (nothing scented or such).
  
• I used two drops of bleach per 1 liter of water, shake and wait 30 minutes, following directions from the EPA Note: some sources suggest using as much as 5 drops of bleach per 1 liter of water
  
• I carried an eye dropper filled with bleach. A lot of water was clear enough to scoop directly into a water bottle, drop in bleach, shake and watch 30 minutes. If the water had stuff in it, we'd scoop dirty water into a pot and then filter through a bandana into a water bottle.
  
  Pro tip: Buy a handful of eye dropper LINK bottles. Mail fresh bottles ahead in resupplies that way you can replace anything that gets damaged. Be sure to label "Bleach" on your bottle so no one gets goofy with it.
  
  I also think it's generally a good idea to have the means to purify water in two ways. For instance, if your Sawyer breaks, it'd be a good idea to have a dropper of bleach available. If your eye dropper springs a hole, it'd be helpful to have iodine, a UV pen, a Sawyer, etc. (even a second bottle of bleach!).
  
  
  
  

I think most of the people here have answered the questions. I'd only say, if you're flying a lot, that having one of the plastic eye droppers is a very good alternative.
I used to work in a pharmacy.

There's a brand I'm missing here, but you get the basic idea. I just worry about glass breaking, not that plastic is indestructible mind you.

Anyhow. If your flying don't forget to wrap your bottle in a quality ziploc bag or two. And some pens need you to relieve air pressure (Pilot 823) in them to prevent the inky mess.

Best of luck. Hope that this one works for you. Cheers.

I had to take a plane two four days ago, and I used nicotine empty bottles for e-cigs. A friend of mine gave them to me, I washed them properly and they're just perfect! You can find something like [them] (http://www.amazon.com/Empty-Dropper-Bottle-Plastic-Liquid/dp/B00DS2B6GE/ref=pd_tcs_compl_hg_63?ie=UTF8&refRID=0XEHBVKEJY7T43MRTKRM) easily.

Oh awesome. I didn't even think of using that type of bottle (the first one) I love it. I'm not sure if you saw it, but here's another option for the future maybe. Thanks again!
