The marvel that you're observing here is a 607-foot, 14,000-square foot "candy carpet" created by artist duo Craig Redman and Karl Maier to promote a shopping center in Chengdu, China. It took 2,000 volunteers five days to put together.
As you can see from the video, the sweets are fully wrapped and presumably protected from the elements, since plans are to donate it to needy kids once the mosaic is disassembled.
