Roger Waters helium-filled two story inflatable pig floated away over the weekend during Waters performance at the Coachella music festival. Concert organizers offered a $10,000 reward for the pig’s return.

Two couples in Southern California found tattered pieces of the pig in their yards. Concert organizers identified the pig remains, and said the reward will be split between the couples.

Susan Stoltz, who found a plastic heap in her driveway Monday, said:

"My kids are going to think I’m so cool."

On another note, Dr. Albert Hofmann, the Swiss chemist who discovered the hallucinogenic drug LSD, died of a heart attack at his home yesterday in Basel at the age of 102. LSD was made illegal after Charles Manson committed unspeakable murders, and other crime erupted in the 1960s. LSD was blamed and banned. Click here to read more about LSD, and Dr. Hofman.

Below is a very old video of British Troops who underwent an experiment where they were given LSD.

Roger Waters, co-founder of Pink Floyd, played Coachella on Sunday. During Waters’ performance his two-story high inflatable pig floated away. He said as it flew away, "That’s my pig." He would like the pig returned. If you’ve seen a flying pig email lostpig@coachella.com. Waters is offering a $10,000 reward. Below is the original version of a great Pink Floyd song called Pigs on The Wing.
