An intriguing aspect of the speaker's collection is the abundance of videos on these specimens—some of which have never been uploaded or shared publicly. These videos document the samples undergoing various effects, such as a "gelification" process where some materials turn into gel-like substances, and a "cracked" or "rotten rubber" appearance seen in others. The speaker mentions that some of these effects resemble decayed or decomposed rubber, hinting at complex chemical or physical processes at work.
