They won't watch unless you do something suspicious. Put the bottle or whatver container in your crotch and you should be fine.

I am going to usethe Quick Fix bottle and subing the synthetic urine with a clean specimen. Check out this link on how Quick Fix works (pick it up at your local head shop, link also has a nice video): Fake Pee Will Beat Any Drug Test! Make sure to check out all of the posts, especially the one sticky one on top of this forum dealing with substitution.

Good luck and give us your results when they come...
