Surely you have already heard that a sealed envelope must be passed over the steam in order to reopen it, right? If you tried this experiment, you soon found that in addition to not being effective, it makes the paper curl ...
If you want to reopen a sealed envelope, here's what you need to do:
- Place the envelope in a plastic bag and place it in the freezer for two hours.
- When you take it out of the freezer, immediately put a knife on the glue and you can open it without breaking it.
In addition, when the envelope is back to room temperature, you can easily seal it again.
