Of Course the easy way would be “PlaceOnPints2” .
Create a can with a Lathe-Nurbs call it “Can”,
copy the can and call it “Drops”.
Crate a Water Drop Texture with Colour, Transparency, Bump, Alpha
and maybe Displacement.
Put a Water- or if you like experiment with a Noise shader in these channels and play the settings
you like best.
With the Texture Axis animate the Offset (X).
You might have to scale down the “Can-Nurbs” a little
to see the drops.
