Physical Comparison and Conditioning of Putty

What happens here

The presenter opens both containers to reveal the putty. He demonstrates the consistency of the regular plumber's putty, noting its light tan/beige color and Play-Doh-like texture. He then shows the non-staining putty, which is slightly more gray and has a similar pliable consistency. He explains that if plumber's putty is not malleable, and appears hard or cracking, it is old and should be discarded as it won't seal effectively. He stresses the importance of keeping plumber's putty in a well-sealed container to maintain its workability.

Goal: Understand the physical properties and proper storage of plumber's putty.
