How are everyday things like toys and bottles manufactured in factories?

Look around the room. The plastic cup, the rubber duck, the cap on your water bottle — every one of them started as something you'd never recognize. Most began life as tiny plastic pellets, smaller than peas, poured by the truckload into machines. The big question is: how does a pile of nibs become a perfect, shiny toy? Let's follow the journey.
First, the pellets get hungry-machine treatment. They're poured into a long heated tube with a giant spinning screw inside, like a corkscrew the size of a log. As the screw turns, it pushes the pellets forward and squeezes them, and the heat melts them into a thick, gooey plastic — about the texture of warm honey or melted cheese.
