Introduction: Impossible Tape
The best part of any puzzle is the solution. Many people believe that knowing how something is done ruins the illusion, but I believe that sharing how something is done brings a greater respect for the process. Having made a few other impossible objects, I thought that combining two tape rolls to form this Impossible Tape roll was the perfect challenge. I selected blue painters tape because it is easy to work with, has a great color, and wasn't too sticky. This process is simple enough that anyone can do it with a couple of rolls of tape and some time. If you make your own impossible tape, be sure to share your pictures!
Step 1: Materials
Step 2: Unwrap Tape
Use gloves to keep your fingerprints and oils off the tape. Unroll the tape inside out onto the spray paint can taking extreme care to not rip the tape.
Step 3: Keep Unrolling
Keep unrolling the tape as straight as possible. It's not the most important to keep it straight, but it will help later on.
Step 4: Link Tape Rolls
Once the tape is completely unraveled, cut apart the cardboard tube. Do this very cleanly and in steps along the cardboard tube. On the inside, be sure to cut along the seam to hide the cut. Link the two rolls together by using white glue or other clear glue. Use tape not found on these two rolls (if you want each roll to be 100% unused) to clamp the glue joint till dry.
Step 5: Roll Back Up
Apply more glue to the cardboard that was previously ripped off the tube and start rolling the tape back up (the tape being rolled onto the cardboard will act as the clamp). Use gravity to keep the roll aligned while rolling everything back together.
Step 6: Make It Look New
No matter how careful you are rolling it back up, it won't look exactly like new as each layer will not be perfectly placed on top of the previous one. Use rough Sandpaper to flatten each side until it looks new. Scuff up each side of the unrolled roll of tape to make sure that both rolls look the same. You can clean up all the adhesive residue and 'sawdust' using a lint free cloth with some acetone.
