Shewing Gum BubbleUsed shewing gum is sticky and difficult to clean.

A hardening-after-use shewing gum would soften when it gets in contact with saliva, i.e. in the mouth, and harden after the contact with saliva has been discontinued.

Technically,  the new shewing gum would react with some typical saliva ingredients for softening and harden after the reaction is discontinued.

Hardening-After-Use Shewing Gum: Temperature-sensitive

A simpler solution would be temperature-sensitive hardening-after-use shewing gum. It would soften when the temperature range is between 36.4 and 37.0 Centigrade, i.e. the temperature of a healthy and hear-to-healthy human body, and harden at any other temperature.

This solution would be easier to implement and it would solve 90% of shewing gum cleaning problems.
