It was the last week before End of Year Exam, we were having revision for some topics taught. Some of them had started their self revision but some did not. Anyway, most of them had some urgency for SA2. They know that this is of utmost importance for them.

I also arranged a Sensory Evaluation for them as a break in between the 2-hour lesson. It's about adding 2 different colourings into the Ice-cream soda. Students got to taste them and learnt about the aesthetics side of food preparation. The results were very interesting. Some said they preferred the pink drink as it's sweeter, while some said they preferred the purple one as they like the colour and it's tastier.

My helper then told them: No sugar was added into any of the drinks prepared. So I rounded-up the sesson by telling them that sensory evaluation is very subjective. There is no right or wrong; and sometimes our eyes would be cheating us. Next time when we are doing 'Sensory
Evaluation' we may have to close our eyes and get a more accurate result.

That reminds me of the Pepsi Challenge...
