See these 2 bags of bulk product from my favorite health food store? (You can double click on the images to enlarge them...)
Same sized bag:
Same color contents:
Yet mixing them up could spell real disaster!
Ever swallowed yeast? Oh the agony!
Ever tried to get light, fluffy rolls by adding a tablespoon of fiber? Let's eat ROCKS!
Here's another one.
Very similar bottles:
VERY different contents!
In case ya don't know, Ginko Biloba increases peripheral circulation and helps your memory (or so they say...), Kava Kava relaxes your muscles and helps you sleep.
Uh-Oh...
