Came across the following puzzle and not having any luck trying to solve it.
"Design a chair to support the weight of a person. You can't use any tape or glue or any other fixing materials. You can use card to make the chair & the structure." Thought about paper mâché but do not have the knowledge to work out the strength of this material but at the back of my mind there is something from articles found in ancient Egyptian tombs that were composed of this. Any clues would be gratefully received
