How to Make a Mason Jar Straw Cup

April 26, 2013

Last week we were performing one of our typical handyman to-do-lists for a client in Calabasas, a little window repair, a smidge of deck maintenance, a drop of drywall repair, when we witnessed our client, a mom of two young children, throwing all her plastic sippy cups out. She had decided, like many other parents, to move away from potentially-chemical-leaking plastic to more environmentally friendly, healthy alternatives. She was headed out on a shopping trip to purchase a dozen pricey metal containers, when our technician mentioned a DIY project he had read about and done for his own kids. Mason jar straw cups. In a half hour, our client had half a dozen new, healthier drinking cups for her family. But you don’t need a minimum of 15 years of experience (like our technicians) to make these beauties. Skill level: beginner, materials: available at your local hardware store. Here are the instructions, as well as a link to our favorite recipes for fruit-infused vitamin water (that our kids love).

Good old-fashioned glass is making a major comeback in food and beverages. The beauty of glass is that it’s better for the environment and better for your health. Here’s why: Glass is made out of 100% recyclable material, made from all-natural and sustainable raw materials and can be reused endlessly without any deterioration in quality or purity.

Unlike some plastics, glass is free of bisphenol-A (BPA) – a known endocrine disruptor, phthalates, PVC, or polycarbonate, so nothing can leach into your water from a glass bottle. This is why drinks always taste better from a glass. For all these reasons, glass is the only food storage packaging generally regarded as safe by the U.S. Food and Drug Administration.

Fun fact: Mason jars were named after John Landis Mason, a young inventor who designed the threaded jar neck design with a metal, screw-on lid in 1858. This familiar jar design is staple in our modern pantries stocked with jars of spaghetti sauce or apple sauce. But at the time, it was a major innovation that changed the way people preserved food and made glass jars reusable.

Materials:

Mason jars in any size (common brands are Kerr, Ball and Mason). They come in a wide variety of sizes such as half pint, pint, quart and half-gallon. Recommended sizes for children are half pint or pint for children and pint or quart for adults.

Drill and 3/8″ drill bit

Rubber gaskets (we used gaskets with an outer diameter (OD) of 9/16″ and inner diameter (ID) of 1/4″

Paper straws

Time: 5 minutes

INSTRUCTIONS

Step 1.

Drill a hole in the lid. You can do this one of two ways:

Option 1: Screw the lid onto the jar tightly and drill the hole while holding the base of the jar as pictured. Warning: There’s a risk of shattering the jar, so proceed carefully on this one.

Option 2: Hold the lid tightly and let it overhang halfway over a sturdy table or surface and drill the hole in the desired spot.

*Or a third option is to use a very sturdy hole puncher instead if you don’t want to use a drill.

Step 2. Take a pliers or wire cutter and clean up any sharp shards.

Step 3. Using the rubber gasket is optional. If you want a truly leak-proof seal or want a more polished look, the gasket is a nice touch. Make sure you clean it thoroughly with soap and water before using.

Insert the rubber gasket. Tip: Push it in and down halfway into the hole until the groove lines up with the lid and then push down on the other side.

Step 4. Insert paper straw. We used eco-friendly, biodegradable paper straws by Kikkerland.

Fill with your beverage of choice and enjoy. We are big fans of these easy-to-make, homemade vitamin water made with fresh fruit and herbs.

      Hi Marti,

      We actually bought those at our local Ace Hardware store. These should be available in any decent hardware store. We asked the clerk and were guided to the right spot. Hope you can find yours locally!

      Best,
      Mr. Handyman
