no, he said with other drinks too. but whatever

He puts a glass rod in his coffee and tells everyone to guess why he does, offers money to the one that comes up with the right, scientific answer. A metal spoon would do as well, I quote. It's not for stirring, nor identifying his cup.

http://makegoodcoffee.com/coffee-talk/coffee-chemistry-from-an-expert/ would this work with a small glass rod too?

then keep the oxygen in the liquid, contain its freshness and taste?

true... could molecules be attracted to the metal or glass? could the hydrogen stick to it or go up to the surface?

The tube does not have an inner diameter, but that would be something worth experimenting! That's the kind of answer I'm looking for :P I'll propose those ideas! thanks!

Yes I have :P

Trust me I've thought about everything outside the box... the box is sealed with multiples layers and I have to open it! :P And that Mad Scientist image is pretty funny :P

I know... well, no wonder he offers money to the one who figures the answer out

This is going to bug me for the rest of my days... :P Same here... my teacher said it was chemistry/physics related... And that it wasn't about the heat of the liquid... So I'm clueless...

I already know the solution isn't stiring. And yes I've seen it, it could be possible... however he did say that the effect could be reproduced using a spoon with any other drink, so i don't think it's for filtering

If it would be as easy as stiring (which we did ask) I would not put this up :P

That's what I thought too but he said that wasn't it... Though when I asked if it was to somewhat keep the liquid's heat (even thought it wouldn't make a big difference...) he said it wasn't it either. Would it be possible for the rod to keep the molecules in movement?

Not really... he just leaves it in there all the time.

Hello All, One of my science teachers puts a glass rod in his coffee, but he won't tell us why... I was wondering if there was a physic/chemistry related explanation to this. He said that the effect did not occur before when he didn't put it in. Adding the glass rod ''solved the...
