Has anyone tried the sugar pregnancy test?

Just for fun, of course. They say urine with hcg in it won't allow the sugar to dissolve, no matter how much you add or how much you stir that it will clump instead. Is there any truth to this? Any confirmed early mommies to be out there wanna try and post the results? Or any one in the tww wanna try? I did the test for fun because my Nonnie told me when I was younger that's how she found out she was pregnant with her first kid.
