I see that my new next door n'bor has a child's inflatable wading pool in the backyard., maybe 8 feet across and a little over a foot high.
It seems to have come an electric airpump and even though I never had one, I know they did not in the 50''s through ???
I presume people blew them up with their mouths back then. How long did that take and did people pass out from too much breathing?
Gernally I don't like these new-fangled more expensive "improvements" but in this if the pump doesn't break right away, it's probably a good idea.
