Avoiding Stinkines: More Convenient Chemistry

My classes are often a bit messy – it’s an unavoidable side effect of doing lots of labs.  That’s ok, but I’d rather avoid the mess when possible.  That’s why these “Magic Color Crystals” are solid favorites in my tool kit.

Using purple cabbage juice to explore pH is time-tested, safe, effective, and fun.  But actually making the purple cabbage juice can be messy and stinky.  Unless you have a really high-powered blender, the easiest way to make purple cabbage juice involves boiling cabbage for an hour or more.  Boiling cabbage for that long leads to a truly smelly kitchen.

These “Magic Color Crystals” from Chemistry Bits are a fabulous alternative – they’re basically a powder made from dried cabbage juice.  Just mix the powder with water and you’re ready to go.  No muss, no fuss, and no weird smells.
