Step 5: Stick the Suction Cup
Note: over time, the suction from the suction cup may loosen the tape. If that happens, your suction cup should still hold, but you might want to just re-rub the adhesive back into the tile.
That's it! Packing tape is clear, so you'll never see it, and it's safe to wash as long as you've sealed down the edges well with your fingernail. It comes right off when you no longer need it, and it will make you muffins for breakfast.
OK, maybe not. Just checking to see if you're still reading. ;-)
