Water powder. still in used?

As I'm busy catching up learning with new gadgets and many other things, I frequently leave my children at mom's place for a few hours. When they come back, you will be amused with 'new thing' that they learned at grandparent's place.

One of the most common 1 is they would say: "Chiak kofee, chiak beehoon! chiak kofee, chiak beehoon" loudly. u know why? they called their grandpa's staff for coffee break... @; ) 2 loud walking speaker which running wild...

Another practise is - they asked me to apply water powder on their face whenever after bath. Kids really catch up new thing fast - both good & bad one...!
