A Tiverton School is hosting its own version of the ice bucket challenge to fundraise for a new library and computers.
Pupils at Bolham Primary School in Tiverton have been told they can dump a digger bucket of icy water over their teachers if they manage to raise £21,000.
The school's head teacher, chair of governors and chair of the PTA are also part of the 'Digger Bucket Challenge'.
The pupil who raises the most will get to push the button that soaks the grown ups.
Bolham Primary has made a video to help the pupils reach their target.
