Kdy\u017e se ohe\u0148 vymkne kontrole, je ohe\u0148 na st\u0159e\u0161e. A to doslova.

\nN\u011bkdy kolem roku 250 p\u0159.n.l. sestrojil jist\u00fd Ctesibius hasi\u010dskou st\u0159\u00edka\u010dku a o pades\u00e1t let pozd\u011bji se o to pokusil i Hero z Alexandrie. Ale velkou d\u00edru do sv\u011bta, tedy do ohn\u011b s nimi neud\u011blali.<\/p>\n

\"\"I ve st\u0159edov\u011bku byl ohe\u0148 postrach. Ohniv\u00fd kohout, jak se po\u017e\u00e1ru \u0159\u00edkalo, rychle p\u0159eskakoval ze st\u0159echy na st\u0159echu. Domy byly \u010dasto d\u0159ev\u011bn\u00e9, nav\u00edc nama\u010dkan\u00e9 jeden na druh\u00fd a do\u0161kov\u00e9 st\u0159echy snadno vzpl\u00e1ly tak rychle, \u017ee k pokus\u016fm o ha\u0161en\u00ed \u010dasto ani nedo\u0161lo.

V roce 1518 vymyslel Anton\u00edn Platner, zlatn\u00edk v n\u011bmeck\u00e9m m\u011bst\u011b Aug\u0161purku, st\u0159\u00edka\u010dku na vodu, ale teprve kdy\u017e na p\u0159elomu 17. a 18. stolet\u00ed amsterodamsk\u00fd mal\u00ed\u0159 a vyn\u00e1lezce Jan van der Heyden p\u0159i\u0161el se zlep\u0161ov\u00e1kem v podob\u011b hadice, za\u010dala b\u00fdt hasi\u010dsk\u00e1 technika \u00fa\u010dinn\u011bj\u0161\u00ed.<\/p>\n
