I love to save my urine is this normal?

I pee in empty Gatorade bottles all the time I cap them and then put them in the windows for a few days until the sun makes them ready to burst. My record is 5 2 liter cold bottles full of urine. Ones they are ready I dumped them out the window and the smell is just lovely I enjoy it my parents are starting to complain that the bsckyard smells like piss. I tell them I am going green by not flushing the Toliet and letting it go into the soil is this normal. I love the smell
