Etymology
borrowed from Yiddish platsn "to crack, split, burst, fizzle out (of a plan)," going back to Middle High German blatzen, platzen "to strike loudly," probably going back to a West Germanic verbal base *platt- (whence also Old English plættan "to strike, slap," ēarplættan "to box the ears," Middle Dutch platten "to strike"), of onomatopoeic origin
Note: The second sense is perhaps through association with Yiddish plats "place."
