1. Toilet humour
   C: What about the modern toilet, can you imagine life before the invention of the toilet? In the past, people went outside to use the toilet so modern toilets are much more convenient. Sir John Harington invented the first toilet for Queen Elizabeth I in 1596 but people thought it was a joke and it wasn't popular. Two hundred years later Alexander Cummings developed a new design and the toilet became popular. Now everybody has a toilet.

2. I can see properly!
   A: Can you imagine life without glasses? Many people have problems with their eyes and they need glasses. In 1262 Roger Bacon discovered that glass can help you see and an Italian inventor, Alessandro di Spina, made the first pair of glasses in 1282. These glasses were very different from the glasses we wear today but they were a really useful invention.

3. Convenience food
   B: How did people open soup before the invention of the tin opener?! This small invention changed the way we eat and what we buy. In the 1860's Ezra Warner created the first tin opener. This was an amazing invention but only shopkeepers had them as they were too big to have at home and difficult to use. Shopkeepers opened the tins for the customers before they left the shop. Finally, in 1870 William Lyman invented the modern tin opener so everybody could open tins at home.
