I brought in a real life gas mask from my very old granddad. I showed the class the gas mask and they thought it was very interesting. The gas mask is 70 years old and nearly falling apart. My granddad was 4 when the war started and his sister Joan was 1. My granddad remembers the tops of the post boxes were painted in this special paint that detected poison gas in the air, so every night people went out with a torch to see if the post  box had changed colour.
