50 is also pouring from too high, increasing splash risks. If he's wearing contacts, then that's a big no-no too. He also appears to be working with hot chemicals (a hot plate is in the foreground) without gloves or tongs. Speaking of hot chemicals, his hot plate is backwards; he'd have to reach over the heating element to adjust temperature. At least he doesn't have long hair hanging around that can catch on fire. On a barely related note, he probably wishes he had had those forehead protectors when
this happened (warning: some rough language).
His rap is boring too... Tupac/2Pac and Public Enemy are vastly superior.
