SUNNY Delight, the orange substance, has been defeated in a blind tasting against a new Indian soft drink made from cow urine.
Researchers asked 30 children to test Sunny Delight against the Indian cow piss and a cup of ground pubes, earwax and horse vomit.
The vitamin-packed treat was then rated against a pint of liquid faeces, a cocktail of cheese juice and sweat drippings from John McCririck's scrotum and a glass of hot water strained through Carol Vorderman's pant-gusset.
'Sunny D', launched in the UK in 1998, was first developed by the CIA to destroy huge swathes of vegetation in South East Asia. It is now produced in a disused zinc mine on the outskirts of Gdansk.
Research chief Tom Logan said: "It was fairly full on to start with. There was a lot of crying and shouting and an awful lot of vomiting, but then we moved on from the Sunny Delight."
Distressed child Emily Bishop, 12, said: "If I drink all the sick, the poo and the sweaty pants, can I just leave the orange one and go home to my mummy?"
Kyle Stephenson, 14, also placed Sunny D at the bottom of his list.
"The faeces was disgusting, but at least it came back up on its own. With the Sunny Delight I had to reach down my own throat and scoop it out with my hands."
He added: "I have to say, the one from Mrs Vorderman's pants was curiously invigorating with a lemony aftertaste. She should bottle it."
