A campaign has been launched in Great Yarmouth in Norfolk to remember 79 people who drowned in 1845.
They were among thousands of people who'd gone to watch a clown sail down the river in a tub pulled by geese.
59 of the dead were children who were on the bridge to watch a widely-advertised stunt to drum up publicity for a circus that had just arrived in the town.
