I'm only new to this internets thing.

This is one of those things that's so old it was covered in mainstream media as well. It's that old.

So if I pull this trick out at a party I'm not going to win any new friends?

well, i hadn't seen it.

I could give you all sorts of chemical reactions to do with household stuff.

Except you cant remember any other than baking soda and vinegar right now, right?
Now here is a thought, is the mentos eruption a physical or chemical reaction?

a lump of sodium in a bucket of water is fun too

do you even know the actual difference between the two?Turbine wrote:Except you cant remember any other than baking soda and vinegar right now, right?

without opening wikipedia or google that is

hay guyz I hear sulphur acif in the I's is hardcore

Physical, I believe. Something about the porous surface of the Mentos acting as a perfect surface for carbonated bubbles to build up rapidly.

I also know of a lot of other household chemical experiments, but most of them are extremely dangerous and can easily kill someone. Great big clouds of chlorine gas for instance.
Also made household explosives once.

Gotta be careful with the gas clouds. Lawsuits and such.obsidian wrote:I also know of a lot of other household chemical experiments, but most of them are extremely dangerous and can easily kill someone. Great big clouds of chlorine gas for instance.

I always do this as a demonstration for my classes, they seem to get a kick out of.
Now, lets hear all of your horribly dangerous home chemistry experiments.

Nucleation! That's the word I was looking for. I spent 15 minutes flipping through the dictionary trying to remember the word. That would have kept me up all night.

Why not spend 1 second on the internets to find it?obsidian wrote:Nucleation! That's the word I was looking for. I spent 15 minutes flipping through the dictionary trying to remember the word. That would have kept me up all night.

Hard to search for terms when you know the definition and application of the word, but not the name of the word itself.

nucleation sites are plentiful on the mentos.obsidian wrote:Hard to search for terms when you know the definition and application of the word, but not the name of the word itself.
BTW - I typed 'bubble forming sites mentos' in google and found nucleation sites in 10 seconds.
