It’s Gesundheit, damnit.

Step 1: Getting Acids

Follow the instructions in the left table below twice, starting at a. Once for the primary acid (pA), and once of the secondary acid (sA). The acids also come with an “Anion” (N), a mass value (AM), and a value X. Z is only used if the unicorn rule applies, and should not be calculated for the secondary acid.

For pA: statement is TRUE/FALSE For sA: statement is FALSE/TRUE
a	SN contains vowel?	Go to b/c
b	Any needies?	Go to d/e
c	SN digits ≥ SN letters?	Go to f/g
d	SN digit sum ≥ 12?	Go to k/h
e	Modules > minutes?^Z	Go to j/i
f	SN odd?	Go to h/n
g	Any D batteries?	Go to i/n
h	Batteries odd?	Go to k/m
i	Ports > Last SN digit	Go to j/l
j	Empty port plate?	Acid is A/B
k	Lit > unlit?	Acid is C/D
l	Ports ≤ indicators?	Acid is E/F
m	SN letter^A sum ≥ 20?	Acid is G/H
n	Lit BOB?	Acid is J/I

	A	N	X	AM	Z
A	HF	F^-	1	20.006	:20
B	H₂SO₄	SO₄^2-	2	98.072	:08
C	HNO₃	NO₃^-	1	63.012	:07
D	H₃PO₄	PO₄^3-	3	97.994	:07
E	HCl	Cl^-	1	36.458	:36
F	HBr	Br^-	1	80.912	:08
G	H₂CO₃	CO₃^2-	2	62.024	:08
H	HBF₄	BF₄^-	1	87.81	:06
I	HC₂H₃O₂	C₂H₃O₂^-	1	60.052	:06
J	HOTf	Tf	1	150.07	:06

^ZIf you are in Zen mode, this is always TRUE. ^AUsing A1Z26.
SN means Serial Number.

Unicorn: If you have exactly 2 batteries in 1 holder and a lit FRK, instead of doing the rest of the manual, press Titrate when the seconds in the timer are Z in the right table above.

Step 2: Getting Bases

Use the table below to get both a primary base (pB) and a secondary base (sB), based on the color of the beaker shown on the module. The bases also come with a “Cation” (C), a mass value (BM), and a value Y (use the instruction below the table).
If there is NOT a BOB, CAR, CLR, MSA, NSA, SIG, or TRN indicator: swap ‘p’s & ‘s’s.*

	pB	sB	pBM	sBM	pC	sC
R	NaHCO₃	KOH	84.006	56.105	Na⁺	K⁺
G	NaOH	KOH	39.997	56.105	Na⁺	K⁺
B	NaOH	NaHCO₃	39.997	84.006	Na⁺	Na⁺
C	LiOH	LiC₄H₉	23.947	64.056	Li⁺	Li⁺
M	NH₃	LiC₄H₉	17.031	64.056	NH₄⁺	Li⁺
Y	NH₃	LiOH	17.031	23.947	NH₄⁺	Li⁺
K/W	NaH	Mg(OH)₂	23.998	58.319	Na⁺	Mg²⁺

Y is 1, except in the case where C is Mg²⁺, in that case Y is 2.

*In case you have strange indicators, this condition is if there are NOT any indicators with any of the following letters: A B C E G L O T.

Step 3: Calculating Acid Amounts

First, use the table below to calculate W depending on the day of the week the bomb started.

Day	Sunday	Monday	Tuesday	Wednesday	Thursday	Friday	Saturday
W	0.5	1.5	1.4	2	2.25	1	0.8125

Next, use the following equations to get the number of drops (D) used for both acids. Note the ceil() function means to round up. If the number of drops ends up being over 99, make it 99.

pD = ceil(((16*W)/pAM*pBM)*(pX/pY))
sD = ceil(((20*W)/sAM*sBM)*(sX/sY))

Step 4: Submission

Use the table below to determine which safety buttons to press for both acid/base pairs, with the acid as the row and the base as the column. Once for primary using the buttons on the left side, and again for secondary using the buttons on the right side. In the table below, G means press the green fan button and RG means press both the green fan button and the red FIL button.

	NaOH	NaHCO₃	KOH	NH₃	LiOH	LiC₄H₉	NaH	Mg(OH)₂
H₂SO₄	G	G	G	RG				RG
HCl	G	RG		RG		RG	RG	RG
HF	RG		G		RG	RG
HBr					RG		G
HC₂H₃O₂	RG	G	RG	G	RG	RG		G
HOTf	G		RG		RG		G	RG
HNO₃		G	G	G	RG		G
H₂CO₃	G			G		RG	RG	G
H₃PO₄	RG	RG	G	RG			RG	RG
HBF₄			RG	RG		G	G	G

After pressing the safety buttons:

Change the top display to pB (using the small buttons on the left).
Press BASES.
Change the top display to the combination of pC and pN (⁺ and ^- cancel out).
Change the numerical display to pD (using the triangular buttons).
Press Titrate.
Press SALTS.
Repeat the above, but with the ‘p’s changed to ‘s’s. The module will solve once Titrate is pressed twice.
