For the warm environment, the spiders were placed in plastic cup enclosures that rested 18 inches below a heat lamp. Prior to starting data collection, the spiders and plastic cup apparatuses for each condition were weighed so that a difference in weight could be detected after four days. The spiders were then left in each condition for four days, and their condition was checked every 12 hours. To avoid from overheating the conditions, the heat lamp was alternated on and off every 12 hours. Following the four days, the plastic cup enclosures were weighed to get a final weight of the spider web in each enclosure.
