This is a video of a dust devil (not to be confused with Dirt Devil, who make dustbusters) making hay dance in a field in West Sussex, England. It's very mesmerizing to watch, and several times I saw shapes appear in the hay, kind of like how when you see things in clouds. I definitely saw a horse and a rooster and an angel and I'm pretty sure I saw my 3rd grader teacher Mrs. Cox in a bikini riding a dolphin. The mind sees what it wants, you know?
Keep going for the video.
Thanks to carey, who agrees the best way to make hay dance is shooting at its feet with your pistols yelling "Dance, hay, dance!"
