can u tell me how it works and how u made it

[13Henriquezm]

Can you make a cold cup hot by doing this or is it just hot to cold

Nice. Does it go faster with or without the teabag ?

Thanks for your rapid reply. You do not need the teabag to make it faster but temperature difference between hot water and atmosphere is important.
