      Lithium is the lightest metal, but it is not very useful – like we can’t make super-light cars with it or anything like that because it is so reactive and it’s really soft! The metal with the best strength to weight ratio is titanium!

      Funnily enough, the metal I got drilled into my thumb bone on tuesday is titanium too! Like i said, super light and super strong!
