I tried them out today with a gummy candy mixture, and they worked great.
We noticed as we were opening our calendars, that many of the candies weren't necessarily Christmas related, there were hearts, moons, clovers, and even squirrels, and elephants, so they are perfect for any time of year.
The shapes were clearer in gummy, than they had been in chocolate too. We were finally able to make out the sleigh, and the pilgrim duck with the cork gun, that appeared as chocolate blobs in our advent calendars. Okay, we're still kind of guessing when it comes to the pilgrim duck - but I think we're getting warmer.
It's great to be a homeschooler.
