Apam Napat

Okay, so APAM NAPAT is actually an acronym that stands for "A Panas Air Masuk, Nak Panas Air Keluar." This phrase is in Bahasa Malaysia and it means "Hot Water In, Hot Water Out."

So let's say you have a bath tub and you want to take a hot bath. You turn on the tap and wait for the water to get hot. Once it's hot enough, you can start filling up the tub with the hot water. This is the "Hot Water In" part of APAM NAPAT.

As you fill up the tub, some of the hot water will start to cool down because it's exposed to the air. But because you want a nice hot bath, you need to keep the water in the tub as hot as possible. So what can you do? You can add more hot water from the tap! This is the "Hot Water Out" part of APAM NAPAT.

Basically, APAM NAPAT is a way of reminding you to continue adding hot water to your bath as needed, so that you can have a nice, hot soak. It's a helpful phrase to remember if you want to enjoy a hot bath, especially during cold weather.
