The other day I was carrying my hot tea with lemon from Dunkin Donuts, and the cup started to leak tea in a way that just baffled me. I poured the tea into a different cup and examined the leaky cup. It appeared to be corrosively eaten away, as if by a chemical. I thought, maybe this was just a defective cup.
But, no. It turns out that lemon oil - which exudes from the peel - can dissolve foam cups.
Which means, I was also drinking some liquefied cup,
while I was drinking that lemon tea up.
