I experimented a lot - I tried smoke, sand, mirrors. In General, everything that can somehow transform, change its shape. I tried to experiment with soap bubbles, but it always turned out badly - it was the early 80's, then few people were engaged in bubbles, and indeed few people knew about them. But I did not give up and kept trying. I locked myself up in my laboratory for a year with different jars and bottles and experimented, until I got a formula that allowed me to play with size and shape. Then I added effects: light, smoke, music.
