One of the techs here at work brought in some leftover cake from her son's first birthday party. For some reason (we haven't asked) she decided that the cake, shaped like a pig face, should be a deep fuchsia. Not that any of you need proof that cake dyes are good for dyeing protein, but I thought I'd share the results.
Imagine if it had been wool, instead. One of the receptionists discovered another effect of the dye, but I'll spare you, dear readers, from a little TMI.
