this was your best video so far. I was curios when i was a kid and decide to do this, but a few attempts i cant do it and wasted a few paper and toilet paper rolls. When I realized this I started gain interest and remembrance when i saw this on RU-vid. After doing some research I have now fully know how it works, and seen some youtube videos the references and now i decided to do it by myself. I have done 2 cylinder in a tutorial in youtube and I have done 2 cylinder by myself without any tutorial and research and only using my mind and thinking and i have done a circle and half circle. And sometimes when i saw your creations i sometimes get it how it works and sometimes confused. And lastly my last sentence, thank you Kokichi Sugihira for doing this creativity and sharing your creativity and I think I will the next you Sir.
