I am a novice but always enjoy following all the info. and using it
in my hobby. I recently had a brainstorm that I am so proud of that
I had to share it!
My son dropped his binoculars into the lake and they were ruined as
even a small amount of water causes fog on lenses. Suddenly, it
occurred to me to use the casting bell jar to boil off the water and
pump it out! Worked perfectly!!! The next day my phone got soaked so
I rushed home with a dark screen and it making funny noises and it
worked perfectly after several minutes in a deep vacuum. We use this
same technique to evacuate water from refrigeration systems. I don’t
know if you can make any money but it saved me $250!!!
