Here's an excerpt from the lab I did in chem class today, encoded as a Caesar cipher:

Ze kyzj vogvizdvek, pfl nzcc jklup kyv vwwvtk fw zetivrjzex kyv tfetvekirkzfe fw re zfezt tfdgfleu fe tfeultkzmzkp.
shift = 17
IN THIS EXPERIMENT, YOU WILL STUDY THE EFFECT OF INCREASING THE CONCENTRATION OF AN IONIC COMPOUND ON CONDUCTIVITY.
Solve this following affine:
YOIMDOMCFSEBIQN
Where N=D and D=N
(It may appear at first that the question is unsolvable due to the a value not being coprime to 26, but the question is actually solveable).
Edit: also something interesting- the encryption key and decryption key are the same.

There may be an issue solving here due to the April Fool's thing.
