Polystyrene are mostly used to protect articles from breaking when sent in packages. A professor of digital arts at University of Oregon, Michael Salter, uses polystyrene to make robot sculptures, formula cars and bikes. His biggest sculpture is a 22 feet tall robot surrounded with small robots to make passers-by keep distance so they don’t accidentally knock it over. Salter creates the sculptures by cutting the polystyrene in pieces and gluing them together, and it took him several months to do it.
