Warm lemonade or cold tea?

Oh no, I was thinking about this exercise for too long. I forgot to drink my lemonade and now it's warm.

Well, that weird. My tea that I made earlier is cold now.

Strange. Touching both, they seem to have the same temperature.

Are you sure? Let me try.

So, what do you think?

I think you are right! They do feel equally warm. But how is that possible?
