Which gum last longer double mint gum or bubble gum?

its not hubba bubba its stride gum, the one that last longer is bubbelicious or either trident gum.

That completely depends on what you mean by 'lasts longer'.

If you are talking about the actual piece of gum, and how long it will last before it disintegrates into nothingness, (or extremely small particles if you want to get technical) then you are talking about a figure that hardly matters anyway, unless you're wondering how long it is before it comes off your shoe.

If you are talking psychologically, ie how long a person can stand there chewing mindlessly before spitting it out, usually onto the ground, then that depends on the individual person's traits, including, but not limited to:

Stubborness, boredness, unawaredness (ie they forget they are chewing gum), tiredness, jaw strength, tooth count (ie number of teeth in their mouth), automatic swallowing reflex and preferred gum flavour.

Which brings us to our next point, which is that you could be talking about how long the flavour of the gum lasts. In general, chewing gum will retain its taste longer than bubble gum, as that is what it was desinged to do (ie provide a nice taste and chewability) whereas bubble gum is used to blow bubbles that end up all over ones face in a delightfully sticky mess.

You however, have singled out bubble gum and mint gum as the only available option, which is very unfair as all the other forms of chewing gum have been excluded from this descussion, and the bubble gum is therefore likely to be able to come up with a flavour that can beat the poor mint gum in long lastingness.

The other variable, one we will not cover in this already frightfully long discussion, is that of the particular type of gum (ie the manufacturer of the gum, such as Hubba Bubba, Willy Wonka or Sugarplum). Undoubtedly they all use different methods of retaining as much flavour as possible.

And Cherry Chewing Gum is the best anyway.
