Valentine Sweethearts

Posted by Picasa

When I heard on NPR that Necco had changed their recipe for Valentine hearts, I had to rush out and buy a variety of Necco Sweethearts and Brach's Conversation Hearts to compare. We did a lot of experiments yesterday.

Here's one thing all the hearts had in common (except the sugar-free ones). Drop them in water, and they sink. But after a while, they bob to the surface again.


  1. All I gotta say is that you better not be wasting Cadbury mini-eggs on experiments!

  2. Actually, I just bought some "Popping Cadbury Mini-Eggs to investigate."
