i like it though ;-)

Yes even if it is fake.

Go down to your nearest chemical supplier and tell them you want 2g of rhubidium and caesium to blow up a bathtub and see what they say in return.

The point of it is to convey that higher metals with a valency of 1 have a higher reactivity and...having fun blowing up bathtubs. :)

@N7SpectreLT of course it is. I do enjoy watching huge explosions, I'm not going to lie. But the fact that so many people think this is real (more specifically them being complete retards bitching at people and claiming to know it for sure "because the internet says so") really bugs me. Yes, it pisses me off. I had to point out that this is fake... and I expected it to get alot of views, which it did, for my measures.

Your missing two important things.

1. The quantity of metal used in the tub is probably bigger than that in the lab in the clips you showed.

2. They are not being 'thrown' in the water. They are put in tubes that sink to the bottom and settle there for a few seconds before going off. The release of hydrogen will be under high pressure that throws water in all directions. It cannot burn until exposed to air, by then it would have expanded. Only H2 that is close to Cs will be purple, rest yellow.

@XtQfH 1. I even added an annotation in the video which points out that they say they're using two grams of rubidium.

2. The heat from the reaction of the caesium with the water creates enough heat to procude some water vapor carrying caesium ions, making the flame from the explosion purple.

Besides, a lot of more serious youtube users (like the official channel of the university of Nottingham) have re-done the experiment and they all came to the conclusion that the Brainiac clip is a fake.

@sciencoking Ok I looked at again. I missed the 2g part (don't see annotations on my iPhone). And I found something on badscience that says theyre fake. I guess you are right. Have an upvote!

@XtQfH Thank you :-)

I think that the poster of this video is correct about the hydrogen. Although the reaction of Cesium and water does create it's own energy, there would be enough heat left over from this initial reaction to ignite the hydrogen in a secondary reaction after hurling all of the water out of the way. This explosion is too clean there should be a big fireball.

@PurplePhury3412 ;P i was just goshing i was hoping someone caught that

@necos Let me see this paper blowing up a mountain.

Also, In my science class the proffesser coated potassium with water and it exploded. I already knew that cesium is stronger than potassium, so I think that Real life > Something a guy off the internet said without any proof.

@eevelutionsfan Getting A's, while still thinking this experiment is real. Kinda makes me feel sad for the university that graduated her aswell....

[eevelutionsfan]

@necos yea sure u did... my mum got A's inb chemy + bio and she is a fully qualifyied teacher who is able to teach. my mum passed her degrees with flying colours, now please i dont wanna fight with some teen who thinks he's so smart , yr just stupid

[necos]

@PurplePhury3412 This doesn't fucking prove anything either. If your wanted to waterproof anything. Covering it with cesium would do nothing btw. It would not be dangerous, because it would SLOWLY react with the water in the air making it harmless.

Also. I once watched a guy who blew up a mountain with a piece of paper. Now i learned that you shuold not bring paper to the mountain because then the mountain would blow up INSTANTLY. Wow i feel smart after i learned that,...

[necos]

@eevelutionsfan No, i am one of the guys who get A in university chemistry and acctually know how it works. Unlike you and your mother

[eevelutionsfan]

@necos dude i pity u for not getting a decent education + My mum is a very good chemistry teacher she made me get the highest in my year in the chemistry module if u dont believe me screw u. i would have never passed with out her help. i got an a* . let me guess yr one of the fellas who's got nothing better to do but just make fun of ppl cause they have no gcse's right?

[PurplePhury3412]

@necos Because blowing up TNT doesn't prove anything. I learnt that I'd be stupid to make waterproof stuff by covering it in Cesium.

@l337tub Thats like saying TNT wont blow up peanuts because, belive it or not, they're one of the ingredients of TNT
