Vyu\u017e\u00edv\u00e1 principu vzn\u00e1\u0161en\u00ed, doch\u00e1z\u00ed zde ke sni\u017eov\u00e1n\u00ed odporu. Jde o prostou fyziku. Vysv\u011btlit lze cel\u00fd mechanismus prost\u0159ednictv\u00edm tzv. Bernoulliho rovnice, co\u017e je vztah u\u017e\u00edvan\u00fd v mechanice tekutin.

Nad k\u0159\u00eddlem je tedy tlak vody mal\u00fd, pod n\u00edm v\u011bt\u0161\u00ed. K\u0159\u00eddlo je proto vytla\u010dov\u00e1no vzh\u016fru.
