How Do Warm Packs Work. Yet the science behind them is. To reuse these hand warmers, boil the closed packet in water to return the crystals to a liquid. How do hand warmers work? The heating effect of hot water bottles declines over time as the water cools, whereas heating pads are electrically connected and provide constant heat. Don’t waste perfectly good heat by throwing out a hand warmer after only a short use! Salts would dissolve in water and act as electrolytes to promote. Reusable hand warmers work a little differently. This phenomenon shows how bond energy can be released. It also shows the importance of chemical engineering and could lead to a section where students design a device (or application) of their own. To activate, simply open the pack. The heating pack can be placed in boiling water and the sodium acetate can be dissolved again. They have a supersaturated sodium acetate solution inside the packet. As the solution crystalizes (sodium being salt), it releases energy as heat. These hotties can reach up to 163 degrees fahrenheit; Oxygen in the air reacts with this powder to yield iron oxide—rust—and heat.
