The other day we were supposed to test the acidity of drinks, which in this case was 7-Up and 100-plus.
Dr K: take 100 mL of the beverage and test it
me: ok (measure carefully 100 mL of drinks into beaker and take to test)
few minutes later,
Dr K: ok, so what did you find out?
me: 100-Plus isotonic drink is more acidic than 7-Up, but 7-up tastes better...
Dr K: Test the acidity then neutralise it!!!!! WTF you drink it for?!?!?!
me: Ooooh @_@ (goes to get more drinks)
