Washer is good, for sure.
I think Tornado is the other Spin, instead of Sling or Whip (although I see the possible connection those could have).
If Tornado (“Eye” -> “Mascara”) is indeed a second answer for Mascara, we would still need one more.
I’m hesitant to go for it here though - if the other team can win next turn it won’t matter, and if they can’t, we can see more words taken off the board.
The problem I’m having is that there are a lot of possible options without anything really strong jumping out. Three of the suggested answers in the first round belonged to the other team!
So I’m seeing:
Pocket (it’s small, fits in a pocket, could be carried around in a pocket for quick application, and I’m not sure, but “Pocket Mascara” might be a thing)
Spot (like blotch, or an area that needs touching up)
Stream (Mascara can run, mimicking a “stream”)
And possibly even Point or Hide…
