V okviru tehni\u0161kega dne za devete razrede je bil del programa namenjen tudi spu\u0161\u010danju raket.
\nU\u010denci sami izdelajo rakete iz dveh plastenk, v katerih so bile gazirane pija\u010de. S tem dose\u017eemo, da je rezervoar za gorivo nekoliko bolj vzdr\u017eljiv na pritiske. Za gorivo se uporabi kar voda, potisno sredstvo pa je zrak. V ta namen smo imeli kompresor za zrak.
\nZadosten pritisk dose\u017eemo \u017ee z ro\u010dno tla\u010dilko za zrak. Letos se kljub spodbudi mentorja noben deveto\u0161olec ni odlo\u010dil, da bi jo prinesel v \u0161olo.
\nIzkazalo se je, da bolj\u0161e rezultate dosegajo rakete, ki so natan\u010dno izdelane.
\nOb rahlem de\u017eju smo pripravili vzletno plo\u0161\u010dad. Vsak u\u010denec je testiral svojo raketo. Tako je sledil najbolj prijeten in zabaven del \u2013 opazovanje parabol leta raket.
\nNekatere rakete so dosegle zelo dobre rezultate. Merili smo dol\u017eino leta. Ena je celo preletela cel poligon in pristala na strehi telovadnice.
\nPo svoje pa so zanimive tudi rakete , ki niso \u010disto pravilno izdelane, saj v zraku izvajajo razne akrobacije in prispevajo k dobri volji u\u010dencev.<\/p>\n

Vsekakor je spu\u0161\u010danje raket zelo zabavno in ga bomo \u0161e ponovili.<\/p>\n
