Durn. You left your mug at home again. But there’s a tall can of beans in the camp cupboard, and a hammer and tin snips in the shed. Get to it.

Step 1: Remove the top and empty and wash the can.

Step 2: Make a cut around the circumference about 2 inches down, but leave a 1-inch-wide vertical strip of can.

Step 3: Tap small folds over the sharp edges. Tamp them down smooth so you won’t slice your lips.

Step 4: Bend the strip down into a handle. Smirk at your buddies while you sip.
