Scientists have come up with a new use for wood. They have a way to make it transparent. This could change the way many things in our lives are used and made. See-through wood could one day replace glass and be used in windows and tables, for iPhone screens, and other building things. The idea has come from researchers at the University of Maryland in the USA. They tried different ways to take out the chemicals from wood that give it colour. Researcher Liangbing Hu said, “We were very surprised by how transparent it could go. This really makes it possible to replace glass and other things.”

The researchers worked with a small block of wood. They boiled it in water for about two hours. The chemical which gives wood its colour, disappeared during the boiling. This left behind colourless chemicals, then you will see transparent wood. The see-through wood is a lot stronger and less dangerous than glass. It is better at stopping against the cold and it can be reused. Research is still in its beginning and the experiment can only be done on 10 cm by 10 cm blocks of wood between paper-thin and a centimeter thick. The researchers will now keep on trying until the transparent wood can be used in our daily life.
