So I seem to have this little addiction of doing things that I shouldn’t. Have you ever noticed that little black nipple at the bottom of the shaving gel cans? Give it a press next time, see what happens. Most of the time you’ll just release a little pressure and some air will come out. If you’re lucky like I was you get half the can of shaving cream to come out.
After this happened I have to press every one of these I see. Good thing I work at a drug store.
