Mason Jar Turned Sippy Cup





Introduction: Mason Jar Turned Sippy Cup

Mason jars have many uses, and here's one more to add to that ever expanding list! Now hipster toddlers can chat legos at the playground while sipping juice!

Glass (read: non-plastic) food and beverage containers for kids are becoming increasingly popular. So lets hack our own version from items that are probably already in your pantry:

- Regular or medium "mouth" mason jar. (I used one 8oz and one 12 oz)
- "Take n Toss" sippy cup heads (the same brand also makes straw heads, which would also work for this project)
- scissors
- marker/ pen

Step 1: Unscrewing

Unscrew the lid from the band on your mason jar.


Step 2: Tracing

That lid will be what we use to trace onto the back side of the TakeNToss cap

Simply hold both the mason jar lid and the sippy cap together and trace the outline of the lid unto the plastic cap. Try to keep as much of the nozzle area as you can. 


Step 3: Cutting

Using a pair of regular scissors, cut out the circular line you just traced. This is easier than it looks. 

Step 4: Taste Testing

Place your newly cut sippy cap onto the jar, and secure with the original jar band. It should fit like a glove!

Fill with a liquid and flip upside down. No liquid should leak from anyplace besides the actual nozzle. If it does, I'm sorry to say that you cut off too much of the sippy cap, and will need to try again. 

That last image shows both the original lid and the sippy cap screwed on. This is GOLDEN if you need to transport a drink without immediate drinking needs. (i.e will not drip)

Step 5: You're Done!

Pat yourself on the back and give your kid some milk. Hopefully they'll sleep like babies!

    I made a similar sippy cup for my two year old son out of a glass jar. I crochet cotton sleeves that slide over the glass so he can't break them. He's put them through a lot and they have never broken. You can also buy silicone sleeves that fit these jars if youre not too crafty. They work too.

    Who gives glass to a vhild, really?

    A person that gives glass to a child is an over achiever parent. Theres nothing wrong with glass. Teach them from the start it's fragile. Before our time were there sippy cups? no..

    im sure its fine, a peanut butter sandwich is far more dangerous.

    Awesome! I live in WV and I can tell you these are perfect Stocking Stuffers! I am definitely sharing this!

    What a cool idea!

    This is way better than having to by the overpriced silicone ones! Thanks! I'm gonna go visit the dollar store and stock up for my next moonshine party! ?

    Cool idea - love the creativity. Couple comments:

    There is a HUGE difference between a glass bottle and a glass sippy cup. Bottle are used by newborns/infants who's parents hold the bottle. If you give an infant a glass bottle and walk away, they usually can only crawl at that age and thus the bottle is close to the ground and unlikely to break.

    Sippy cups are meant to train kids how to use a real cup. They get dropped from high chairs, thrown when kids have tantrums, etc. Sippy cups are used by toddlers (age 12 months or so) that can walk. Anyone who has had a toddler knows they are prone to throwing everything. I just caught a TV remote in the face a couple days ago from my 12 month old. No way I would give my kid a glass sippy cup.

    However, put a beer cozy on that thing, and you are good to go. Use a little adhesive so it doesn't come off, keeps the milk cold. Done and done.

    Love the creativity. Thanks for sharing.

    So many haters! I love this idea bc I love mason jars. I'm gonna put sippie cup tops on all my mason jars when giving out shine as Xmas gifts this year.
