I was playing Survival mode with some friends, and then one of them made a campfire. Jokingly I got some sand and tried to make glass on the campfire, and the sand started floating on the campfire. Then later I tried it in Creative. And same with redsand, it started floating on the campfire! It just looks weird, but I don't really want to remove it. Just wanted to point it out. Plus, it's the closest thing we now have to the rosebush trick! 

Sunny days,
