How does the Thermoller work?
The Thermoller is activated by water. The packaging will include a funnel for using purposes (it will also include a bag that you can carry the Thermoller in). When you bring this device outside with you, it will contain two bottles of cold water (you can refill and place inside after each use), used to activate the ammonium chloride when needed. You will first fill the Thermoller with eight bottles of water (or less).
