We all like to play with colored balls, don’t we? But the Conveyor Belt Experiment needs not only a couple but plenty of them - as conveyance objects to sort out.

The Upper Austria based company Eurofoam has sponsored these balls. The special PUR-coating gives the balls their colors and a nice finish.
