More Fun with Ice: The Time Bomb

The fun with ice continues! In ongoing experiments freezing things in ice, I decided to try freezing food coloring in the middle of an ice cube. Then when the ice melts, the coloring will release and change the drink. Click on the link below to see how I did it and what happened. The first step was to make perfectly clear ice. Then I heated the stubby end of a bar spoon in a pot of boiling water and kept plunging it into the ice until I made a tunnel. Then I added several drops of food coloring. After I... Read more →

Using Salt Walter as an Insulator to Make Clear Ice

This blog post is a continuation of this experiment. In this experiment, I wanted to test out another way to insulate an ice cube tray to make clear ice. Inspired by a comment from another blog entry by a reader named Gael, I decided to try salt water as an insulator rather than just plain water as in the last experiment. If it worked, this would be a way to make clear ice at home without taking up too much freezer space. I took a small food container and put it into a slightly larger one. The smaller container held... Read more →

Making Clear Ice Without a Cooler

In a set of experiments, I showed that you can make clear ice by controling the direction of freezing. The container I've been using for this is an Igloo cooler. When using it, the ice freezes from the top-down and all the cloudiness in the ice forms at the bottom of the container rather than in the middle of the block. I wanted to show that you can do this without a cooler as long as you have some sort of insultation that accomplishes the same thing as the cooler. In this case, I chose a bigger pool of water...

A Homemade Giant, Crystal Clear Ice Cube Tray

As you're probably aware, I've been dabbling in experiments making clear ice at home. [update: An organized index of ice experiments on Alcademics can be found here.] The way I've found that works best is to freeze ice in an Igloo cooler with the top off. (Please read the post before you tell me to boil the water in the comments- it doesn't work.) This is now how I make all my ice at home- I haven't used trays in months. Now I am working on ways to best carve ice and also trying to create an ice cube tray... Read more →
