It's easy to wax nostalgic about the past until our actual brain kicks in and we remember stuff. I can't even begin to tell you how much I hated ice trays. I remember my brother losing some tongue skin on the bottom of one of those metal ones. I had enough sense to know that if I made the mistake of grabbing one with a wet hand to either wait a bit or put it under running water. And I never ran my tongue along the bottom of one.
What was strange was how sometimes when you pulled that handle it would crack just fine and other times? Well, other times nothing really happened. I also remember all the family arguments and "blame games' over who put an empty ice tray back in the freezer. Not fun.
At some point in the 70's everyone tossed those aluminum skin rippers and got the blue plastic ice trays:
They seemed all modern and neat and always worked like a charm when they were new. After they got old, either you had to hold them under hot water for a few minutes to get the ice out, or worse, they'd just break.
The reason I thought about this today was because I had to hand wash some dishes (oh yeah, that's another thing I don't miss - having to hand wash ALL the dishes!). For years, I had trained myself to crack and refill the ice trays after washing the dishes as a way to also rinse the suds out of the sink and sort of conserve water. So sometimes that old, well-trained part of my brain kicks in. I pull the stopper out of the sink, the water runs out and I think: ice trays. But now I just laugh.
