Having a temperature of 20 degrees below freezing will make your moment dull especially if you are just sitting doing nothing. Because of the cold temperature, employees of the village chairlift that has metal chairs like of a garden chair hanging from a cable offered the skiers a square of cardboard to sit on as insulation. These cardboards would sometime fall from the chairlift and children from the locale will pick them up, sit on it and they will eventually off down to the ski runs. That is where the rennpappe or racing cardboards is born. During the race, student participants are tasked to create a sport apparatus using cardboards from the streets. With this aim, landfills that causes harm to the environment will surely be lessen.
