I sure you have heard of the whizinator. I have heard lots of good & bad things. Personalley i have used it once for an observed PO test. It worked, but i was so anxious the whole time. I undid the clasp while he was behind filling the paper out and pinched the tip. When he came around with the cup i unpichned it and filled it up. You have to be very carful with the clasp or it will make a very obvious clicking. (I am working on modifying the clasp, i will post when finished) It took nerves of steel, lots of practice with it, and some luck thrown in there. BEWARE THOUGH, do a search for "Whizinator caught" and read the horror stories. In my county, using a whizzinator is a felony
