^^ how did you do the "indirect link " Blob ???
it's just through the tinyURL website. That website lets you shorten URLs, and the links go through them.

I almost "fell" for it. Took me a whole 45 seconds, though. [emoji58]

Chemistry in Pictures — RADIOACTIVITY LIVE! In this short movie, you can...RADIOACTIVITY LIVE!
In this short movie, you can watch radioactivity in action thanks to a cloud chamber, a plastic box cooled to –30 °C and filled with isopropyl alcohol vapor. For this demonstration, Julien Simon placed a 0.3-cm³ lump of a radioactive uranium-containing mineral called uraninite inside the chamber. α-Particles and β-particles—the two kinds of radiation given off by uranium-235 and uranium-238—hurdle through the chamber, hitting the alcohol molecules floating around. Because the particles are charged, they rip electrons off or add electrons to the alcohol molecules. This in turn gives the molecules a charge, which then makes them attract noncharged molecules around them. When the molecules bunch together, they make visible white clouds that trace the paths of the ejected particles. α-Particles produce straight, thick clouds, while β-particles create longer, more erratic ones.
