I've seen the "Rainbow Water" idea as a number of different pins and decided to give it a try. Everyone's drinks looked so fun and cool!
The Original Pin
One mom just used food coloring to color the ice cubes, then put the cubes in a regular cup of water. Another mom froze Koolaid into cubes then put that in water. Another mom froze Koolaid into cubes and put them in lemon lime soda.
I decided to make MiO ice cubes since we don't have Kool Aid in the house usually. I squirt a little bit of different flavors (to get different colors) of MiO in each compartment of the ice tray (since a little MiO goes a long way), then filled the tray with water. Once the cubes were frozen solid I plunked them in a glass and filled it with cold water.
Disappointment. This picture is taken probably about 60 seconds after I filled the glass. Those cubes melted SO fast! And there was only about 2 seconds of color layering before they all just blended together. The ice cubes melted a lot faster than normal and they all floated to the top, erasing any layering that went on. And as careful as I was to try and use just a little bit of MiO, it was WAY too strong. Undrinkably so. Perhaps next time I'll just stick to the original idea and do food coloring and water or Kool-Aid and Sprite and see how that works.
