A giant water slide has been set up in Chard town centre.
During the course of the day up to 300 hundred people are expected to head down it.
The event was the brainchild of Mayor Jenny Kenton, who's hoping the slide will help put Chard on the map.
Money raised from the event will go to the Mayor’s five charities – Chard Museum, Chard and Crewkerne After Stroke Care, Chard Carers Support Group, Chard Town Team and Chard Area Youth Committee.
The event replicates an event in Bristol earlier this year, which saw people travel from all over the country to take part.
The slide is open for everyone over the age of six. Those under 1.20 metres tall will be able to head down later in the afternoon when the slide is shortened to allow younger children to take part.
The mother of murder victim Catherine Wells-Burr will be at an event today to mark the 40th anniversary of Victim Support. Since Catherine was murdered in Somerset in 2012, her parents have supported families in similar situations and campaigned for victims' rights.
Jayne Wells-Burr will be at a reception held by the Lord Mayor to celebrate the work of the charity, in Bristol.
