Those several gallium-sellers suddenly vanished off eBay.
Gallium's somewhat expensive. I'd still not ordered any for play time. S upposedly paint it on glass for instant 1st-surface mirrors. Can I vacuum- bend a glass sheet, for a crude Newtonian with a several-meters FL? Get th e stuff all over skin and clothing? (Liquid gallium: it's not mercury!)
Holy crap, the price came down to around $30 for a quarter pound! Not on e Bay, but several sources are on Amazon.
I just got my order today. The package says "metal rod." Yeah, as long a s the room temp is low.
