Kratki znanstveni poizkusi

This video was recorded at RTK 2011 - Tekmovanje ACM v znanju računalništva. Film je posnet z mobilnim telefonom. V filmu pa sta prikazana dva zanimiva znanstvena poizkusa. Prvi poizkus prikazuje kako lahko z reakcijo med kisom in sodo bikarbono ali natrijevim hidrogenkarbonatom (NaHCO3) kjer nastane ogljikov dioksid (CO2) s katerim lahko ugasnemo plamene svečk, ker je težji od zraka. Drugi poizkus tudi prikazuje kako ugasniti svečko ne da bi jo upihnili ali se je dotaknili. Vendar pri tem poizkusu svečka ugasne zaradi porabe kisika ne pa zaradi ogljikovega dioksida kot je bilo v prvem poizkus.
