The science behind the beauty of freezing soap bubbles

To create our frozen ice bubbles we experimented with different versions of a recipe we found on the Twitter account of Chris Ratzlaff (@ratzlaff).
 
200 mL of water
35 mL corn syrup or glycerine
35 mL dish soap
2 tbsp of sugar
 
 We discovered that it was easier to make larger, more stable bubbles, on cold flat surfaces. In the above video we used a frost-covered picnic table. We found it easier to produce the bubbles if we also had some of the soap solution in the drinking straw
