Cost: Pack of seven Silicone Stretch lids, $15.94 on Amazon

OK, I’ll admit I’m part of the problem. Sometimes I see those ads on Facebook and I buy stuff. I don’t do it often, but enough to encourage those companies to keep junking up our feeds. This one was at least a semi-success.

It was a pack of several stretchy silicone lids designed so you can tug the edges over any size container (I’d say up to 15 inches wide) to seal it, presumably replacing the need for plastic wrap (which is the most dratted, infuriating, humiliating, ridiculous use of petroleum ever devised) and aluminum foil (which has its pros and cons).

The first thing I tried one of the lids on was probably not a fair test. These lids appear to prefer metal or glass containers with thin, angular rims — without lips — such as cans or straight-edged mixing bowls. I put my first lid on a plastic bowl that had a rounded inch-wide lip. It sort of worked.

OK, it didn’t really work. It stayed on at least for the time it took me to put the bowl into the freezer, but when I went to retrieve it, the lid had slipped off of one side. Later, however, I tried a smaller size lid stretched over a stoneware cereal bowl of strawberries, and that worked rather well.

These things don’t take up much space. The whole package of seven came in a small envelope, so if I manage to find a handy place to store them in my kitchen (which is in desperate need of a reorganization), I’ll probably use them more often. I got them because most of my mixing bowls don’t have lids and I hate plastic wrap, in case you were still wondering after my earlier diatribe. (And don’t go on to me about Glad Press and Seal. That’s what I use, but I hate it only slightly less than the clear wrap.)

Anyway, the silicone stretchy lids will probably be something my son and his future life partner will find in my kitchen after I die and laugh about, as we do about avocado-colored Tupperware, but for the moment, they’re pretty useful. Just don’t try to find them on Facebook, as I did. All the companies that used to sell them there now seem to have nothing more than links to Amazon.com, where they’re cheaper than what I bought them for.
