Basic question, please don't say temperature change, because i've tried, and it never gets back to same elasticity!

There must be some other chemistry at work.

Even with luke warm water or room temperature water it gets substantially hard.

  • $\begingroup$ Related: Why does gum get harder to chew after a while? Personally, I never noticed the gum altering it's hardness even when I was a kid and consumed all kinds of garbage drinks while chewing the gum. I suspect it might be a subjective matter, or an effect from a particular brand only. It would be more helpful if you could back up your observations by a statistically significant number of similar precedents described in a literature. $\endgroup$ – andselisk Apr 25 at 4:56
  • $\begingroup$ Just for statistic, I have noticed the same. Consistent hardening of the chewing gum after drinking. Just not sure it is brand independent, and even flavour independent :) but I was mostly chewing mint ones :) $\endgroup$ – Alchimista Apr 25 at 7:21
  • $\begingroup$ @andselisk that's too much to ask from an software engineer, but yeah, I'll try to collect some data on it from colleagues, but that won't be random sampling, so have to deal with it. And what would be the benefit of such exercise BTW? Also it seems not related as the affect discussed in question in about hardening after chewing a while, i am specifically seeking for hardening after drinking water along gum in mouth. $\endgroup$ – Bhanu Chhabra Apr 25 at 13:12
  • $\begingroup$ Chewing gum can be made from quite a number of base materials, PIB, PVA, polyisoprene, mastic (arabic gum), Manilkara chicle, and many others (en.wikipedia.org/wiki/Chewing_gum has a list). I'll guess the effect (which I have also observed i think) will depend a lot on what you actually have. $\endgroup$ – Karl Apr 25 at 18:10
  • $\begingroup$ @BhanuChhabra I'm not asking you to social poll. I suggested that since it might be a subjective matter, adding some data from third-party researchers would be helpful. $\endgroup$ – andselisk Apr 25 at 19:42
