While many people have been helping clean up the devastation caused by the meteor which came down in the Russian Urals last week, others have been searching the shores of Lake Chebarkul- which it is thought to have struck - for tiny fragments of the space rock.
Scientists and members of the public are looking for small holes in the snow that indicate fragments of meteorite below - which they plan to hold on to as keepsakes or sell on to collectors and researchers.
BBC Russian's Oleg Boldyrev reports.
