Pas mal comme bricolage quasi non chimique pour Halloween.
A voir si ça marche dans toutes les latitudes / températures / air / humidité ?!? Ils annoncent:
Note: Wind is a killer. Any air movement will ruin the effect. Also, ambient humidity (more is better) and temperature (lower is better) will impact the effect. If performance is not what you want, you can help things out by spraying your lawn with water to increase the humidity at ground level and the fog should hang longer.
