 And with me in the studio, I've also got a set of weighing scales and a ruler. So I'm thinking, I'm thinking we know we have 1.4 million kilometres of cable running at the bottom of the ocean. So if we weigh this little bit of cable and work out how long it is, we can work out how much that 1.4 million kilometres of cable weighs. So how much cable did you buy? It's about seven centimetres.
