Conducted a small experiment

So I decided to do some late night baking because why not. But I only had one cookie sheet and had batter left in my piping bag. So while one batch was resting and baking, I just let my piping bag sit on my table, with the big end folded over to prevent more air getting in there. Then when the first batch was baked and cooled, I cleaned my mat with vinegar, let that dry, then piped that same leftover batter, let THOSE dry and let them bake! Surprisingly, they all still had feet! They were hollow and fragile though, but nonetheless, would probably mature nicely. First pic is the batch I used right away, second batch is the one that had to wait longer. I just thought that was neat and wanted to share.
