    Believe it or not, if you want to you can create a Prandtl–Glauert singularity all of your own. You need two things, however: a whip and a humid day. If you can do an Indiana Jones and successfully crack the whip then you should be able to see the effect. When the whip is cracked then a perceptible cloud is produced at the position where the tip of the whip attains transonic speed. Maybe this is not something to be tried at home after all.
