Suppose you're on a train or on an airplane, going on vacation. And darts a piece of chewing gum stick to your clothing. Enough pressure and time have been applied so that it doesn't come off right completely. But it is not totally baked in there for days though.
How do you get it off? Any hacks?
Now, typically that might not be a question for this site - I suppose there are detergents or solutions you can get which attack the gum but not the fabric. But you are on the road and have limited access to these items you might use. So please prefer answers that are executable as early as possible (that is, "wait till you're home and then" is not a great start for an answer.)
Notes :
- If you want to limit your answer to a specific material - cotton.
