/sci/ - Science & Math

Posted this a couple of days ago, reposting to get new ideas

In my country we have this science-themed tv-show which has a decent prize and as I was selected to the 1st round (the talent round), I need some help. The show is intended for people aged 16-24 (I'm 17) and 15 people will qualify to the next round (I have no idea how many they have selected for the 1st round)
In the first round, I need to show the judges something that would make them select me as one of the 15 who will progress to the next shows. From there on it will be a show consisting of 3 teams (every time one player from the loser team is eliminated), so I really only need help getting into the 2nd round.
The experiment/speech/whatever thing, should take a minute or so (maybe a bit more) and the main idea is that it should be interesting, cool, inspiring or something along those lines. If you have any cool ideas or something, please help me. I would really appreciate it.
TL;DR: Recommend cool experiments for a science-themed tv-show's talent round

Hey faggot, I ain't goin' anywhere so make with the magicy sciency explanation shit.
