Would you drink your blood and urine? You sure would if they tasted like sour candy. Imagine the looks on your friends faces as you throw, what looks like urine, down your throat, directly from a urine sample container, or blood from a blood vial. Well, believe it or not, you can pull a prank like this, by using the Sour Candy Body Fluids, from Think Geek. The “urine” tastes like concentrated lemonade, only very sour, and the”blood” is actually sour cherry syrup. Have fun, tricking your grossed-out friends.
