We had some fund for Halloween by unleashing three chemists to destroy pumpkins in three different ways... In the name of education of course!

 

The three methods were smashing (with liquid nitrogen), burning with alcoholic gel and setting off a kilogram of thermite!!

Any other suggested methods?

Thank you and thanks for watching... The reason we keep going and enjoy it so much is because people keep watching them! We always love reading the comments on YouTube... well, most of them!

I too have a very small youtube channel. If you're remotely interested, check it out. http://www.youtube.com/hermanntrude Any suggestions will probably be cheerfully ignored in the full knowledge that I can't be bothered to change anything :0)

I would give it to thermite but that will lay the hurtin on anything, so i'm going to go with the nice crisp shatter of the frozen pumpkin. Fire color loses, nothing cataclysmic happened to mr. pumpkin.

thermite was definitely the way to go. It nicely made thoughts of firework night and halloween mix together.

hi cool video, what was the last thing.

Al + FeO? I just understood something with very hot iron...

Or could someone clarify this for me, the reaction and it's reactants?

 

thx

interesting, thank you. I saw it in the first post too now,

That was thermite, the equation for it is Fe2O3 (s) + 2 Al (s) = Al2O3 (s) + 2 Fe (s)

It is a very hot and dangerous experiment, it gets hot enough to melt the iron it produces.
