In this week's video, Brent continues to investigate products made with steam. Today, we discuss polystyrene cups. These styrofoam cups keep your cool beverages cold and your hot beverages hot.
These cups are made from tiny polystyrene beads the size of sugar crystals that are combined with steam (pentane gas and heat). The heat and gas cause the beads to expand to 40 times their original size.
Once the polystyrene cools into giant rectangle molds, they send it off to make styrofoam cups.
Watch the video below for a full breakdown on the correlation between styrofoam and steam. Be sure to subscribe to our Youtube channel and tune in every Friday for our latest Steam Culture.
