Hot Ice Directions

Creating hot ice is a fun science project for children of all ages. The main ingredient in hot ice is sodium acetate--the same chemical used in salt and vinegar flavored potato chips and hand and foot warmers sold at camping supply stores. The sodium acetate creates an exothermic reaction, which means it gets warm when it creates the ice-like structure. One of the most fun uses for this chemical is creating hot ice in your home.

Instructions

• 1

  Create sodium acetate using one liter of clear vinegar and four tablespoons of baking soda. Dissolve this in 150 ml of water. If you have sodium acetate, use a similar amount of the chemical with the same amount of water.

• 2

  Stir continuously until the water can no longer absorb the sodium acetate.

• 3

  Pour the liquid in to a glass container, being careful not to transfer any undissolved sodium acetate crystals.

• 4

  Cool the mixture in the refrigerator or freezer.

• 5

  Take the mixture out of the refrigerator or freezer and bring to room temperature.

• 6

  Touch the liquid and be prepared to be amazed! Ice will start to grow from the place where your finger touches the liquid and will rapidly turn all of the liquid in the container to ice.
