Kummakivi is a 5,00000 kg rock in Finland that has been balancing on top of another rock for 11,000 years.

This strange sight perplexed visitors since its discovery, and spawned stories of giants having balanced the rock in its position, but geologists have a more realistic explanation: glaciers. This isn’t the first balancing rock to be discovered, and scientists believe that glaciers - capable of carrying such a heavy rock with them - left it behind as they receded to the North over 8,000 years ago. The power of glaciers trumps even giants.

The Kummakivi Balancing Rock is a natural feature found in a scenic forest region of Ruokolahti, a municipality in the region of South Karelia, in the southeastern part of Finland. This feature consists of two boulders, one perched precariously on the top of the other. Although the upper rock looks as though it would roll off at any given moment, this has not happened. Additionally, if a human being were to apply force to the rock, it would not budge even the slightest bit.
