There are 15 different outputs. Sorting input by fire and non-fire always work for the 9 outputs where input doesn't have at least one water and salt. The left side builds a secondary stick and covers the rest of 6 outputs over 3 drop attempts.

Now the fun part of dropping two molecules with output conditional is that if first molecule succeeds the second molecule could then succeed for next input. This then leads to some future tape loop where both molecules do not match. I don't want to build for disposing two sticks in 15R so instead I put in wanding so the main stick only attempts drop when the secondary stick fails all 3 attempts.
