Rubidium dropped in water!!! Another experiment in our "small metallic collider" (aka, the anti-climax machine). We suspect this is the last time you will see it in action. More chemistry at http://www.periodicvideos.com/

  • About this brainiac stuff. In brainiac they used dissolving glass which allowed the Rb to sink to the bottom of the bath and then uniformly react with the water, creating a shockwave which was transmitted fully to the bathtub making it break,

  • @ConnorXV

    Really?

    A lot of people seem to think the those reactions were perhaps assisted by other explosives to create a bigger bang....?

    If they did such a thing, I'm sure it was all in the name of inspiring interest among their younger viewers, of course! ;)

    Here on @periodicvideos we'll always just show you what happens, even when it goes wrong (actually, especially when it goes wrong!)

  • @periodicvideos Brainiac admitted to "enhancing" the explosion with 'splodey stuff...

  • The energy released increases per atom, not necessarily per mass, and since rubidium atoms (and caesium) are much larger and heavier than sodium or potassium you might not get the huge explosion you are looking for.

  • HURRY UP AND F**KING DROP IT INTO THE F**KING WATER!!!!!!!!!

  • I think it failed because when te hamer struck the vial it may have somehow split the block or weakened it so that way it could come apart after the initial explosion...better luck with francium :P

  • @mikidof wow, that was a long time ago, yes now I know it was a bit of a fake (very exciting to watch at the time though), the number of people brainiac might have brought to enjoy science though might be quite a large one so as long as it isn't an outright lie to real science (ok it was a little over the top) it is quite a good thing :)

  • @ConnorXV the braniac thing was fake... but im sure you know it by now

  • @periodicvideos thats why were watching! And because of the intrest in Science!

  • I can't fap to this! I require a much larger explosion!

    Bring out the cesium!

  • Man the three of you could have had a piss up with that 65 quid
