Hershey Chocolate Sawdust

A long, long time ago, I microwaved some Hershey bars so that I could demonstrate chocolate bloom at a school visit. The chocolate bars developed lovely circular chocolate bloom structures, which I passed around the classroom to make the students goggle.


Then I put them on the fridge and forgot about them. Little did I know I was conducting a brand-new candy experiment!

When I finally took the plate down a year and a half later, this is what I found:
The chocolate had bloomed so much it had crumbled to pieces, like chocolate sawdust. (If you don't believe it's actually chocolate, look for the Hershey's logo on the bar on the upper right.)

All that was left of each bar was a pile of powder, which I was able to spoon up without any trouble at all.

  1. Have you ever experimented with Cadbury Flakes? I feel like they would bloom to crumble very quickly considering their already delicate texture.

  2. No, I've never played with them. I bet they would be fun!

  3. I am happy I came across this today. Last night I found a forgotten (for 3+years) chocolate coin on top of our microwave. It freaked me out...but now I see it is a looooong chemistry experiment! I am assuming it would not be toxic--do you know?

  4. It might taste kind of grainy if you eat it, but it is fine to eat.
