Our canteen has this machine to make the tea (full video here). It is quite extraordinary. It turns the mundane exercise of getting a cup of tea into a major entertainment extravaganza. The machine is called the "Lipton T-Bird" and is part of their "Tea Revolution". It even has a big yellow light that flashes periodically when the machine is not in use, to remind you that it is still there and is very important.
The key question is: What is the difference between a normal cup of tea and a cup of tea made in this machine?
Answer: 30 pence.
