Seen it twice now and love it. I loved the ampules with the black slime and have found some pretty good reference photos online so thought I have a go at a mini version for the mantle piece! Picked up a cheap vase which, when turned upside down is a pretty good base for the shape. Filled all the ridges in the vase and the top. I think it's a little narrow at the bottom and will probably cut a couple of inches off, but not a bad start. Reckon it's about 3/4 the size of the smallest ones in the film. Think I'll do a rough cast to cut the lid off and carve the alien text in the surface.
If anyone has any good ref photos I'd really appreciated it / dimensions.
