I understand the proclivity to try/do crazy stuff at that age... or at any age really if you have the inclination to do it (or if your're Colin Furze).
At about 16-17 I tried a hydrogen making experiment in a beer bottle and lit it up thinking it will burn with a steady flame. It nearly blew my face off.
My advice is not to back up from these kind of things, but to think beforehand exactly how much risk you're exposing yourself and others to and taking all the necessary measures to minimize those risks. If your gut is telling you this might not end well, then listen to that instinct. And of course, don't do anything so stupid that it ends up hurting not only you, but others (random example: flying a RC plane without any training in an area with people - that's stupid and there are probably legal consequences if someone gets hurt). Today's safety culture is both a blessing and a curse that just dumbs down children's curiosity to understand and be fascinated by the world.
