Sealing Test: PTFE Thread Seal Tape Around a Cup's Rim

In this experiment, we conducted a sealing test by wrapping thread seal tape (commonly known as PTFE tape or plumber's

tape) around the rim of a cup to evaluate its effectiveness in creating a watertight seal. Thread seal tape is widely used in

plumbing to prevent leaks, and this test aimed to explore its potential application in other scenarios, such as creating a

temporary seal for containers.
