Why You Should Put an Envelope in the Freezer
Try this little trick next time you forget to put something in an envelope.
I like to mail cash for family birthdays, but sometimes I forget to include the money before sealing the envelope. My solution is to place the envelope in the freezer for an hour or so. The seal opens up without any problem so I can fill the envelope and tape the letter shut before sending it on its way. – James Staley
