    "description": "Met dit boek bouw je je eigen, 70 centimeter hoge knikkerbaan helemaal zelf van papier! Laat twee knikkers tegen elkaar racen door ze op hun eigen startpunt te laten beginnen en ze door trechters, toffe tunnels, zwaartekracht tartende loopings en steile hellingen naar beneden te laten razen. Het enige wat je nodig hebt is dit boek, wat plakband en ... knikkers natuurlijk! Je kunt alle onderdelen makkelijk uit dit boek drukken en met behulp van de instructies makkelijk aan elkaar maken. Zo bouw je steeds hoger en hoger, tot je eigen knikkerbaan klaar is en de strijd kan losbarsten. <br />",
