I decided to make it real.
(If you haven't realised by now, I'm making a real version of XKCD strip #88, "What Would Escher Do?".)
Step 1: The Needings
You will need...
- A silicon wristband.
- A very sharp knife
- Gorilla Glue*
- Clear adhesive tape
*Before using Gorilla Glue, I tried this with super glue (failed) and welding with the heat of a soldering iron (failed). If you find another method for sticking silicon bands together, please leave a comment about it.
Step 2: The Cutting
(If you're going to decorate your band, now is the time to do it, because you can lay it flat.)
Turn one cut end through 180°, and tape the two cut ends back together, on only one side.
Step 3: The Gluings
If you're using Gorilla Glue*, use a twist of paper towel to lightly dampen one face, and another twist to apply a light smear of glue to the other.
Close up the joint, and use another piece of tape to close it tightly.
Leave the band taped up for at least two hours before checking the strength of the joint.
(*If you're using a different glue, such as a cyanoacrylate "crazy" or "super" glue, make sure you follow their instructions...)
