Canning Jar to Travel Cup

Max demonstrating Step 5

I saw this really sweet product that turns your canning jar into a travel cup. Essentially, it's a molded plastic lid with a sippy hole that fits inside the ring and screws on. I was going to buy a ton of these, then I realized:

Totally hackable.

Materials:
Canning jar
Canning jar ring
Canning jar lid
Flat plastic lid (from yogurt/take out/etc)
Pen/marker
Scissors
Small knife (optional)

Step 1: Take a canning jar lid and trace it on to the plastic lid.

Step 2: Cut it out.

Step 3: Cut an X in the plastic lid to insert a straw. (stabbing with a knife works well) OR Cut a square/rectangle close to the edge to use it as a sippy (it helps to cut a small x opposite the square for air release).

Step 4: Assemble the jar using your plastic lid instead of the metal lid. (duh) Insert straw & tasty beverage.

Step 5: Enjoy!
