OK, clearly my encyclopedic knowledge of DW is much less than I thought (so, much healthier, then!), so I didn't pick up all the references in this month' "Blogs of Doom" for all the spacejunk Sam Seeley has picked up prior to the Nestene sphere.
Who can help me identify the rest?
{Spoiler}
Sink plungers & egg whisks - Dalek
Metal heads with handles - Cybermen
Silver balls that roll all over the place beeping - ?
Green seed pods - Kyrnoid
Stone that that makes the holder reveal intimate & distressing truths about themselves - ?
Rock giving off purple smoke - ?
Big blue bulb giving off golden squares - is that the thing from "The Woman that Fell to Earth"?
Police box appearing from nowhere - no wait, that one I know already.
