  Kudos for covering a "failed" experiment the way you did! It emphasizes that an outcome is a valid outcome no matter if it was negative, positive, expected or unexpected. Imagine where the world would be if scientific papers were published like that. I think I might have to join your patreon just because of this. Keep up the excellent work!

  Ben is showing how to do ACTUAL science on this channel.  Excellent work!

  As a chemist with years of experience in crystallography, synthetical as well as analytical: You are doing great! There are always so many variables, but you seem to have built a good intuition already. Respect.<br><br>Maybe the poor performance is due to the geometry of the fiberes? Even If the spheres reflect the light, the probability of it getting absorbed in the 3d structure of the fabric is just too high.

  As others have pointed out, the lack of radiative cooling might be due to the geometry of the cotton fibers at a microscopic level. The chance that heat radiated from the fibers will actually exit the cloth is much lower than the chance that the heat will get stuck in the cloth and continue to bounce around. I think all things considered it may be worth trying a fabric like Denim or Silk, which has a much tighter-nit structure at the microscopic level. It might also be worth trying to apply the solution to only one side of the fabric, as denim and silk both have flat faces compared to cotton, meaning it may be possible to apply the solution explicitly to the outside of the fabric.

  We&apos;re one step closer to the mythical pillow that&apos;s always cold on both sides. Keep up the good work, I salute you 🖖<br><br>EDIT: even if it didn&apos;t work as well as you hoped, I bet you find a way to fix it. If there&apos;s one thing I&apos;ve learned from watching this channel, it&apos;s that it&apos;s never a good idea to underestimate NightHawkInLight!

  &quot;Even in the failures, we&apos;re learning things&quot;<br>That&apos;s what separates a non-satisfactory result from a true failure; if we learn anything then it&apos;s just an extra unanticipated step towards success.<br><br>The process of making something interesting and useful with home-brew is already a great thing to share, and the extra effort of trying to make it easily accessible for the average-joe is on another level that I really appreciate.

  Cotton fibers are single cells that get elongated and stretched inside the seed pods, so this is the reason why they look kinda like transparent plastic straws, or like transparent long tubular leafs of grass (which are multicelular, I&apos;m just saying they look alike).

  Don’t forget to link your other videos that you’re referencing! You’re the reason I joined patreon and I’m so proud of you. Your experiments are useful and interesting, and your processes are consistently well documented. Well worth crowdfunding.

  Back in the 1970&apos;s or 80&apos;s I started seeing things that changed colors by temperature like mood rings and digital temperature strips for monitoring aquarium temperatures. If a roof/exterior could change to a dark color in winter and a lighter color in summer, it could make a big difference in heating and cooling a house.

  Your failures only show your successes to be that much more legitimate. In the world of sensationalism, your honesty is invaluable. Well done!

  This would be great for hardhats too. They trap heat and get very uncomfortable over time. Even if you had to reapply every now and again if it keeps my head cool it would &nbsp;be a game changer.

  I love this CaCO3 series, i&apos;m in the last year of my chemistry masters and my project this year involves synthesising CaCO3 microspheres (vaterite) for drug delivery purposes. I&apos;m hoping to apply for a PhD with my current supervisor and exploring new applications. This work is excellent and i&apos;m looking forward to seeing more!
