Water normally freezes at 273.15 K (0 C or 32 F) however it can also be "supercooled" at standard pressure down to its crystal homogeneous nucleation at almost 224.8 K (−48.3 C/−55 F).[2][3] The process of supercooling requires that water be pure and free of nucleation sites, which can be achieved by processes like reverse osmosis, but the cooling itself does not require any specialised technique. If water is cooled at a rate on the order of 106 K/s, the crystal nucleation can be avoided and water becomes a glass. Its glass transition temperature is much colder and harder to determine, but studies estimate it at about 165 K (−108 C/−162.4 F).[4] Glassy water can be heated up to approximately 150 K (−123 C/−189.4 F).[3] In the range of temperatures between 231 K (−42 C/−43.6 F) and 150 K (−123 C/−189.4 F) experiments find only crystal ice.
Look at the one that was frozen, you can see it has air bubbles in it. That would be a nucleation site.
