A friend of mine visiting Spain sent me this photo of a couple of street performers seemingly defying the laws of science. She was curious as to how it might have been done.
This is a variation on a very old levitation trick that originated in India and you can see the explanation in the video below.
In the case of the photo, I suspect that there is a steel rod holding up a seat that is hidden under the robes of the upper ‘monk’ that passes down through the bamboo and down the robed arm of the lower monk and goes to a flat base that the lower ‘monk’ sits on to provide the support. It requires some delicate positioning to prevent the whole thing toppling over.
It is nicely done.
