Question: What is your favourite chemistry experiment and why?

John Wenger answered on 12 Nov 2014:

Hi there,

I do quite a few demonstrations of chemical reactions in my lectures and magic shows. I do some nice reactions bubble and froth over and others that make loud bangs and explosions!
I think my favourite is the reaction of potassium with water – it is very explosive and gives out a huge bang and water goes flying everywhere.

Have a look at this video to see how wild it is!

Please don’t ask your chemistry teacher to do it though….it might blow up the lab!
