This tutorial will show you how to make a useless covered spoon originally designed by kkstudio (pictured above). See the entire design series "The Uncomfortable" at http://www.kkstudio.gr/projects/the-uncomfortable.

Step 1: Gather Materials and Tools
You will need the following:
1. disposable plastic spoons (minimum 2)
3. soldering iron (alternatively, a cigarette lighter will work)
4. sand paper (180-grit or finer recommended)
Step 2: Cut Spoon to Make a Cover
Cut one of your spoons to form a cover. Here I've chosen a symmetric form that covers half of the spoon. But there are many other forms of covers that will make a useless spoon as well!
Step 3: Sand Edge of Cover
Gently sand the cover to remove any rough edges. Do this now because it will be difficult after you have soldered it onto the spoon.
Step 4: Tack Sanded Spoon Cover in Place
Before creating a watertight weld, tack the cover in place to keep it from shifting position.
Be sure to open a window for ventilation prior to soldering.
Grasp a fresh spoon and your cover together with one hand. Touch the soldering iron in a few points to tack the cover to the spoon.
Step 5: Solder Cover to Create Watertight Seal
Using a gentle back and forth motion, solder the cover in place. Make sure you penetrate deep enough so that the weld will hold after sanding. But be careful not to solder too deep or your final spoon will look ragged even after sanding.
Step 6: Sand to Form a Smooth Edge
Carefully sand the weld to remove excess material and form a smooth edge. You may need to weld again if you sand too deep. Repeat welding and sanding as necessary until you are happy with the edge formed between the conventional spoon and your new cover.
Step 7: Admire Your Finished Useless Covered Spoon
Isn't it wonderfully useless!
