This metal foil called 'Window' was used during World War 2. Great bundles of these foil strips were dropped from aeroplanes to fool enemy radar. The foil confuses the signals picked up by the radar and gives the illusion that there are a lot more aircraft around than there actually is. These original pieces of window are very fragile and have been laminated to keep them safe so they can be loaned to schools within the evacuee's suitcase.
