So, take for instance what happened today...

The kids were drinking these like, energy drinks or something, and I wanted to say "what is that"
I would just say "Sore wa nan desu ka?".

Also, how would i pose the question:

"Is that water?"

Edit, alright... im trying to figure this out:

Would it be:

"Sore wa mizu desu ka?"
