A surveyor from Edinburgh is to spend two month on the remote island of Rockall to raise money for Help the Heroes. He will spend his time in an eight foot water tank, sprayed with foam insulation to protect himself from the cold.

Only four people in total have ever slept on Rockall, but Nick Hancock, 30, says he is confidant that he can do it;

“The RockPod survival shelter I have constructed is almost complete. It was recently insulated with sprayed insulation, and I am now finishing it internally.”
