Psychologists at Oxford University have shown that tea and coffee tastes better in glass cups than paper cups, and attributed this to purely psychological factors.
Psychologist Charles Spence explained that the weight of the cup makes us think the drink inside is of better quality, while the paper cups suggest that the product we drink is not good enough.
Professor Spence tested his theory on a group of volunteers to experience a drink labeled "A" and another labeled "B".
In their answers, all volunteers agreed that they preferred the drink in Cup A and that the B drink did not have the same quality.
Professor Spence later revealed that the cups bore the same drink, and the only difference was that he added 30 grams to the bottom of Cup A and explained: "What we feel in our hands can have a big impact in determining what we taste."
The psychologist pointed out that our minds see weight as a sign of quality, and there is no physical evidence to prove that the taste of tea changes or is affected by the cup in which it was placed, but it is due to our psychological feeling that the taste of things best in cups.
The University of Oxford physicist Stephen Blandell applied his experience on glass and paper cups to test the quality of tea after he poured it. The tea in the glass cup cools faster than the paper cup, because the paper cup contains many layers with some air gaps, Insulator is very good.
