I tested this out, and I don't think it's reliable. I'm 20 weeks pregnant, and when I mixed equal parts urine and bleach, nothing happened lol. Got a few little bubbles on the top, but not frothing like you're supposed to get when pregnant.

If you believe you're pregnant, take another hpt and go see your doctor. Best of luck to you ^)

I have never heard of this. So one part urine (I'm guessing first morning urine would be best) in a cup, to that add one part bleach - or the other way around? Then mix? Or just leave there and see what happens? And I'm meant to see frothing? It should happen immediately? In 3 mins time?

Now this sounds interesting!

To Lucidity,
Yes equal parts of urine and bleach, in no time the mixture should bubble up and fizz over the cup like soda poured into a cup. Very frothy and like a boiling pot haha. Happens immediately, it's very interesting.

This doesn't work and is extremely dangerous!!! Ammonia and bleach mixed together create toxic gases. Inhaling these can poison u and destroy tissues such as ur trachea, esophagus and lungs. If u wanna test for pregnancy, go to a dollar store and buy a test.

I don't think it's accurate. I tried it last month and it fizzed way over the top of the cup I was super excited and had my best friend do it and the test do the same exact thing.. Neither of us were pregnant and we took multiple HPT.
