Saffron sells for about $7/gram.

An olympic pool, according to wikipedia, has a volume of 2,500,000 liters. Saffron has a density of 0.14 grams/cubic centimeter, or 142 grams/liter. 

142 x 2,500,000= 355,000,000	

355,000,000 grams x $7/gram= $2,485,000,000. 2 and a half billion.

Welcome to the high life.

EDIT: Who the fuck gave me gold and why?
