To use a click heat pack, bend the small metal disc inside, which will trigger a rapid crystallization and heat the pack to around 130 degrees Fahrenheit within seconds. After it cools and hardens, you can recharge it by boiling it.
Step-by-Step Instructions:
- Activate the Heat Pack: Locate the small metal disc inside the gel pack.
- Bend the Disc: Firmly bend the metal disc back and forth. You should hear a clicking sound. This initiates a chain reaction that causes the liquid to crystallize and release heat.
- Knead the Pack: Once activated, the pack will begin to solidify. Knead it gently to distribute the heat evenly. It will heat up very quickly.
- Apply as Needed: Apply the heat pack to the desired area for soothing warmth. Be cautious, as the initial temperature can be quite high. Use a cloth barrier if needed.
Recharging the Click Heat Pack:
Once the heat pack has cooled and solidified, you can recharge it to its liquid state for reuse.
- Prepare Boiling Water: Bring a pot of water to a rolling boil.
- Place the Pack in Water: Wrap the solidified heat pack in a cloth to prevent it from sticking to the pot and potentially melting. Carefully place the wrapped pack in the boiling water.
- Boil Until Clear: Continue boiling the pack until all the crystals have dissolved and the liquid inside is completely clear again. This usually takes about 5-10 minutes.
- Remove and Cool: Carefully remove the pack from the boiling water using tongs. Place it on a heat-resistant surface to cool completely. Make sure the cloth is still underneath it, and allow it to cool. Be careful, as the pack will be very hot.
- Store for Future Use: Once cooled, the heat pack is ready to be used again. Store it in its liquid state until needed.
Important Notes:
- Always use caution when handling hot items to avoid burns.
- Make sure to wrap the pack in a cloth when boiling to prevent damage to the pack or the pot.
- If the pack doesn't fully return to its liquid state after boiling, continue boiling for a few more minutes.
- Avoid bending the metal disc while the pack is hot and in a solidified state, as this could damage it.
