— I’ve got a neighbour, his name’s Nikolai. He’s very kind and jolly and we like to drink beer together. It worked out that how we drink beer is very interesting. We open our bottles, each of us sitting on his own porch, and flick our bottles tops onto the other’s territory. After a while quite a lot of those bottle tops had gathered there. That is, the grass in front of my house had become very messed up, full of all those tops. From time to time this caused some problems between me and my wife. Naturally enough, she didn’t like all that mess. And so, after a row, I started to clear away those tops. I filled up two pockets with them. And as I was picking them up, walking around our house, I started to think of how I could put them to some use. It would’ve been a shame just to chuck them all away. Put I couldn’t think of anything so I just stuck them all in the shed. Then, suddenly, the idea sprung upon me. I’d seen those tops flattened out on someone’s porch. They’d served two functions. They stopped you slipping in winter and they got rid of mud from your boots so that you didn’t drag a load of dirt into the house. The problem was though that I’ve got a brick porch and so there was no way I was going to be able to hammer bottle tops into it. I thought and thought but nothing sprang to mind (…) Then my brother came to stay. When we were in the shed he asked me, "Why have you got all these bottle tops hanging about?" I told him like and, well, he worked at a factory and said that he’d help me do something with them. So, well, a week later he brought me some plastic textolite with openings in it. I had some material left over, some improvised stuff, where the screws are, where the home-made rivets fix in these bottle tops. Well, that’s basically how it all came about.
