The village with almost 900 inhabitants has only a short history as a separate entity. It was founded in 1958, when numerous Myjava kopanice were separated from Vrbový. It was named Prašník after the largest of them. With an area of 2,788 hectares, it is the third largest and seven kilometers long and longest village in the Piešťany district.
The anther has a water mill in its symbol. In the past, the Holeška stream powered up to twenty-four wooden mill wheels. Of the mills with typical names, such as Lajdov, Fajnorov, Podkolesársky, but also Dobrovodské, Kopecký or Bórov, none of them grind flour anymore. The first, the elders, were called "shreds" because they only ground roughly. Newer mills have already produced all kinds of flour from wheat, rye and barley. When they drilled a source of drinking water about fifty years ago, Holeška lost its power and the "milling" began to decline. The last, most modern, U Mockov closed its gates in 2006. In the cadastre of the village, which is registered in the list of protected areas Natura 2000, there are several protected sites. The Veľká Pec Cave has the character of a rock overhang and is declared a protected natural creation. It is also an important archaeological site in which, in addition to the remains of human settlement, a number of fossilized finds have been found, e.g. mammoth bones. Prašník can rightly be considered the gateway to the Myjava digs.
