This is the amusing moment builders jumped on a plank to sink a pillar using their weight.
Footage shows the workers stomping on the plank to push the concrete deeper into the earth in Bangkok, Thailand, on April 21.
Surprisingly, it was effective and the pillar easily sank each time the builder stomped while singing a song to make the atmosphere more relaxing.
Onlooker Thadet Saensee said: ‘The workers were very creative. They were able to finish the job with less effort.’
