Frozen Pee Container

Hello, I was wondering if this is an effective way to freeze urine.

Have someone pee in a water bottle and screw the cap on airtight, place that water bottle inside of a tubaware container and put the tubaware container in the freezer door.

This is what I have done and its frozen ice pee right now inside the bottle inside the tubaware container. Will this be good still?

Thanks in advance.

Yep. Works fine
