If آپ take a Vitamin water (so far it has worked with Dragon fruit, بلوبیری acacia pom and grape...put them in the freezer door for anywhere from to 2 - 3.5 hours. And then check every once in a while to make sure they aren't frozen at all but they feel really cold without any crystal formation at all! Be careful with the acacia and Bluberry casue it cools and freezes faser...anyway, take it out of the freezer while it is still liquid but very cold usually takes 3 hours if آپ leave it just in the freezer door and don't check it مزید than once in between. Anyway, when آپ take it out لپیٹ, لفاف کریں the سب, سب سے اوپر of the bottle on a hard surface and immediatley flip it up-right آپ can watch it turn into crystals before your eyes. The crystal reaction, I believe (x science teacher) is due to the fact that all the minerals in the water allow it to get below freezing temp without atully freezing, but when آپ take it out of the freezer and hit the bottle on the میز, جدول it triggers a crystal to form which triggers other crystals and before آپ have it, آپ have an entire chain reaction of very fine crystal formation!! Taks a spoon and enjoy the very soft and fine textured slushy!! Try it! The crystal bursting دکھائیں in the bottle is worth it alone!! Karen Hoffman RN and X science teacher :)
