In the old days, a swimming pool was a big hole in the ground lined with
concrete. But no more! Today's pools are made by just dropping a flexible
lining in the hole, and that lining is made from PVC. Of course, above ground pools
like this one you see above have used PVC liners for years.
This hot tub, which is good for relaxing, or making several hundred
gallons of split pea soup if the need arises, is also made of polymers.
The surface is made of poly(methyl methacrylate). That's the same stuff as
Plexiglas.
Swimming is fun, but drowning isn't. This life preserver can keep that
from happening. It is made of styrofoam, which is a form of polystyrene. The rope around it is also made of
polymers. It's made of nylon. Nylon stands up
to water better than cotton or hemp rope. (Cotton and hemp are made of
polymers, too, by the way, a polymer called cellulose.)
Playing in the pool is always more fun with inflatable toys, made out of
polyethylene and sometimes PVC. As we all know, the kids love the
inflatable pool vacuum cleaner toy most of all.
Swimming is one of the most effective exercises when it comes to burning
calories, but thanks to this floating pool chair your time in the water
can be spent just as lethargically as if you were inside watching TV!
The webbing on chairs like this is made from polypropylene. The arm rests, which are also
the pontoons which make the chair float, are hollow boxes made of polyethylene.
Also for the aquatic couch potato is the float you see dwarfing Stacy.
The outside is made of PVC and the inside is made
of styrofoam to make it float. (Remember that's polystyrene.)
Pools are fun, but they're work, too. With these nylon nets we can keep leaves and dead bugs out of the pool.
