It’s odd to hear Pete Smith delivering a more straight narrative, but he does it quite authoritatively as we see a few historical scenarios that illustrate just how the accidental discovery of an element that glowed in the dark led Marie Curie to discover this highly toxic element that was amongst the rarest on earth. It needed a mammoth degree of refining from it’s source ore to yield the tiniest amount of it’s salt but this process revealed, somewhat miraculously, that despite it’s lethal qualities it also had remarkable curative powers, too! It’s quite a revelatory short feature this that demonstrates just how much luck and sheer determination, especially at times in history when technology didn’t exist, was involved and the significant levels of danger faced by those who experimented with this newfound chemical. Indeed, throughout it’s development there were many fatalities amongst the scientific community as the potential of radium was explored. Many of these science features can be terribly dry and uninteresting, but this one stays quite watchable for ten minutes.
