I recently heard about how to make crystal clear ice, and one day I was really bored so I decided to try it, but make it colored!
Step 1: Gather Materials
All you are going to need for this is a measuring cup, food coloring, an ice tray, and water!
Step 2: Boiling
First, pour about 1 1/3 cups of water into a measuring cup (depending on your ice cube tray) and boil in microwave for 3:30 min. After it has cooled, boil it one more time and let it cool. This eliminates dissolved air and decomposes minerals in the water.
Step 3: Freezing
After the water has cooled for the second time pour it into the ice cube tray and put 1-3 drops of food coloring in each little cup of water. Then put it in the freezer overnight and let it freeze. Some tips for this step are: -Fill each little cup with water just below the top so the colors don't mix -Use something to carefully stir the food coloring into the water -Be as careful as you can when moving the ice tray into the freezer, one tiny wrong move could mix two colors and ruin the whole thing
Step 4: Enjoy
After the colored water has frozen, pop it out of the tray into your choice of drink and enjoy! PS. Because of the color, it looks the best in water, but since its still just ice you can put it in any drink you want. Also be prepared because when it starts to melt it gets messy! You could also substitute something like flavors for the food coloring and add some flavor to your boring water!
