For various reasons we wanted to create a lightweight material that is stiff enough to build some flying objects out of it. After researching we found out, that Styropor could be used to create very lightweight, yet sturdy sheets. We call this material “StyroPaper” because it is very thin (approximately 0.5 to 0.8 Millimeters) and could be folded, cut or glued – nearly like paper. A detailed view of the material could be found here, where we also discuss the properties of this material.
