Coffee for Free

AFTER only 6 hours of sleep, forced myself to wake up early in the morning for chemistry class. Mr Subra (tuition teacher) extended today's class from 11am to 1.15am

9.00am-10.00am = Fresh and steady condition
10.00am-10.30am = *Yawn* Eye lids were falling.
10.30am-11.00am = Awake. Lucky I had a candy in my pencil case.
11.00am-11.15am = SUPER fresh! It was break time. Bought an egg tart and a Yakult drink each for myself and Lai Kuan. At first she told me that she didnt want to eat but end up finishing them =)
11.15am-1.00pm = Normal state. No catalyst were added thus no action and reaction happened.

While walking back to the LRT station after tuition, I got this drink from Starbucks outside its Kotaraya store. I think they were doing some promotion for the new drink. Anyone know what coffee bevarage is this?
