Thank you. It's taken long enough, but we seem to have gotten there in the end. I'll confess to loading the Argon brochure onto my kindle and looking through it several times a day ;)

I think Quickie are aiming for the Noble gases, though next up, IIRC are Krypton and Neon, one sounds like it belongs in a comic and fails in the presence of kryptonite, and the other just sounds flashy. If they move onto the halogens then I guess the Chlorine will make you green with envy, while the Bromine will just brown you off ;)
