Today I'm bringing you two covers from Practical Mechanics, both of which were for articles on making your own underwater equipment. Unfortunately they didn't credit their artists so I don't know who painted these.
The first issue, from January 1955, gives details on how to make an aqualung. I wonder how many people successfully managed it?
I'm afraid I don't have a copy of the first issue so if you want to make your own aqualung you'll have to look elsewhere. I do have a copy of the second though and you can see how to make your own camera housing here.
