From the German Wiki (roughly translated): > Commercially available irons are used for ironing. In places where no electrical power supply is available or cannot be used due to humidity, the heating plate is heated by auxiliary constructions (mostly gas cookers). For the World Cup, for example, a process was developed in which the iron is heated inside by an exothermic reaction, generated by mixing a hygroscopic chemical pressed into granules with water. https://de.wikipedia.org/wiki/Extremb%C3%BCgeln |
