Gotta say @nancyramirez, my cousin used that foam for her whole wedding day in Houston and it honestly turned into a MESS by the reception. She was outside for photos for maybe 20 minutes and the whole thing went soft and started sliding around. I felt so bad for her because the ceremony itself was pretty long and by the end she looked like she had been sweating through it, even though it wasn't that hot. She ended up having to use a ton of hairspray just to keep it from drooping, but it still felt sticky to the touch. Definitely not a good look for a full day event in this humid climate.

Did you manage to salvage your important notes? My friend had her whole gym bag flood and her training log got soaked, she ended up taking pictures of each page before they dried all stuck together. It was a total mess but at least she saved the info.

But the cornstarch ones are supposed to break down in a proper compost setup, maybe your pile just wasn't hot enough. That soupy mess is actually a good sign they're working.
