DIY Drinking Straws From Stainless Steel Tubing - Material Selection and Guidance

Featured

Off the shelf SS drinking straws are often unsatisfactory for 2 primary reasons:

  • Too thin (not enough fluid flow)
  • Too tall (too easy to knock the cup over, poke an eye out, or accidentally pick a booger)

But, a straw should be easy to DIY. It's a tube. No welding. No joinery. It's an empty tube...full of opportunity.

You get to decide fluid flow, quality, and height. This Instructable is *not* about cutting a piece of metal. It's about designing and making a straw that's custom and right for you.

One 36" piece of high-grade stainless steel will make 3 or 4 straws.

Make. Give. Enjoy.

Step 1: Choose the Right Internal Diameter (ID)

This is the first and most important step. Most pre-made SS drinking straws on the market have a super narrow internal diameter.

A pink Braums straw has the perfect ID in my opinion. It works very well for both water and malts. So, I set out to find a stick of SS tubing with a similar ID.

Nice. This would be great for cold drinks in the summer.

It is. Just be sure that if you make a smoothie, then put it in the freezer, you let the straw defrost before drinking. Else you may have a Christmas Story moment.
