Edible glass? As a mom, I’m sure to keep broken glass pieces away from my kids. This project, however, is more fun with words than anything dangerous. Edible glass is made from a few ingredients and is a simply fascinating creation. Want to make something that is typically not see through or transparent–our food–and make it look just like glass?
These kind of projects that teach and entertain are my favorites! Unexpected learning moments are my way of helping the kids keep their curiosity strong. Take for example, windows. We peer through them everyday to see the world right outside of us. When you can see completely through an object, it’s called transparent. Glass in windows is often transparent. If only some light comes through, like with a curtain or a piece of paper, it’s called translucent. And if no light passes through, like with a basketball or book, the object is opaque.
Most foods are opaque with a few exceptions like some fruit slices, gelatin, and sugar creations like rock candy or edible glass. I found that making something like this, that feels impossible to my children, led to lots of awesome oooh’s and aaah’s!
To create your own sugar glass, here are the materials you need are:
- 1 cup granulated sugar
- 1/3 cup water
- 1/3 cup light corn syrup
- Flat pan
- Aluminum foil
- A candy thermometer
- Optional: food coloring/flavored syrup
- Line your pan with aluminum foil.
- In a medium saucepan, over medium heat, pour in the sugar.
- Add in the water and stir continuously.
- Add the light corn syrup. Keep a constant stir going until the candy thermometer reads 300 degrees F. Remember to do this activity WITH an adult, stirring at this high temperature for a few minutes can get very hot for small hands. For us, this process was about 10 minutes long. The mixture will bubble and pop. If you want to add flavoring or color, do this right before you pour it out. Make sure not to add to much and make your glass opaque! We added a couple of drops of blue food coloring.
- Once you’ve hit 300 degrees, quickly pour out the mixture into the pan. Let it cool for at least 15 minutes.
- Carefully lift off the glass sheet. Hold it up to the light and enjoy the bubbles and patterns you find. When you’re ready, crack, break, and enjoy!
