I've never seen anyone pour super cooled water into another container, and initiate the freeze using an ice cube, so I really wanted to try that. The effect is seen in the blue glass, and the clear glass in the video and, in my opinion, was worth the effort! To get this effect, I put multiple unopened bottles of "PUREFLO" bottled water in the freezer for 2 hours and 45 minutes exactly. The purified water gets supercooled, and when it touches an ice crystal, it turns instantly to ice. It will also do this if the bottle is hit hard enough. This was a really fun project, and one of my favorites because it's safe, awe inspiring, and anyone can do it.
