Look at old windows that have been in for decades. Do they pile up on the bottom like caramel? No. Myth busted.
I actually believed that myth for ages because the panes in my childhood house were thicker on the bottom than on the top, causing visible distortion. Turns out that making perfectly flat sheets of glass was difficult at the time it was built, and that for whatever reason they’d been put in thick side down.
