Hi Olga, no Photoshop, glue, selotape or strings, the photo is exactly as it was taken. A very powerful magnetic force field was created enabling the coins to stay put when balanced on each other. You need the patience of a saint and a very steady hand, they will fall over quite easily. Took me about an hour to create these three piles, cheers Ted
