Mason Jar Travel Cup HACK: Homemade Cuppow/EcoJarz Sip Cup

January 26th, 2014 - filed under: The Farm » Home


First things first! Thank you SO MUCH for all the love and well wishes on my Birthday Love List last week. Celebrations and school were keeping me extra busy, but of course I read each comment, and every single one of them made my birthday so much better. So thank you!!! And now, on to the post . . .


Every time I post a photo or tweet or Instagram featuring the Cupow and/or the EcoJarz lids, I’m met with a flurry of excitement and interest. Everyone wants to know what they are and where to get them, which makes sense, because basically they are AWESOMESAUCE and I use mine pretty much every day.

Last week I was dropping Waits off at preschool, sitting together on the eating blanket (outdoor preschool, remember) with an EcoJarz-lidded green smoothie between us. And when his teacher saw the lid she did what everyone else does . . . well at least what every hippie does. Lots of excitement, and lots of questions.

But this time, there was a twist! Because she then proceeded to tell me that she had seen someone make a similar device using a 1/2 gallon orange juice carton – the kind with a pour spout and lid – and I was like OMG GENIUS and immediately went home and made one for myself.

Like this:

And it works! Totally water tight, at least through a few uses (long enough to drink another 1/2 gallon of almond milk, at least in this house). See?


Don’t get me wrong, I still love my Cupow and my EcoJarz lids, and I’ll continue to use them every day. But from now on, I’m sending Waits off to preschool and play dates with this awesome DIY option, and I won’t have to worry about being out $9 if something gets lost or broken.

    The brilliance of this!!! I have a Cuppow, but it keeps disappearing on me and giving me a sad feeling in my heart. I am going to be SO excited to seriously stock up on this DIY version.

    Just made one of these, per your instructions. WOW! Doesn’t leak, lid screws back on, didn’t have to buy a thing. Genius! I gave it to my goddaughter to carry her smoothie home…stuck a couple of rubberbands around the mason jar for better grippiness, and waved goodbye. Thanks SO much for sharing this.

    I felt like the dumb blonde when I looked at this picture of the cupow!! I was trying to figure how you got a whole punched into the inside cap of the mason jar???? It wasn’t til about 4-5 minutes of scratching my head that I said, “I must be missing something or she’s got incredible mommy strength to cut through that cap!” Then I realized it was a piece of cardboard from a juice or half n half container….oooh mi godddd like I am so blonde!!” lol Thanks for this idea, cool.
