The social experiment was set up by the SOS Mayday action network in a bid to raise awareness about the thousands of children suffering in war-torn Syria.

"We tested the kind-heartedness of the Norwegian people," the group explains on its website.
"The situation for children in Syria is difficult. They live in fear and the nights are very cold.
"Most live in inhuman conditions, many in broken homes without heating.
"To help children in areas around Damascus and Aleppo, we give out winter jackets that they will not freeze at night."
