How the internet works is explained using the example of pigeons in their nests. All the pigeons or computers are connected together, and this is called a network. The rules of how the messages are sent are called protocols, and large messages are broken into small parts called packets. Each pigeon's nest has a number called an IP address, and these numbers can be found on a domain name server which is like a computer address book. The routers send the message to the computer.
In a large space, children could demonstrate how the internet works in a similar way to the pigeons in the clip. The children could have different roles - computers, connectors (by holding hands), routers, a domain name server and packets. Each child could wear a sign which says what they are, and they could be asked questions about their role
