For the control and cool conditions, the spiders were placed in a plastic cup which was enclosed in a Styrofoam box; the cool condition had a layer of ice underneath the plastic cup with a cardboard barrier to achieve the cool temperature. The spiders in the heated condition were kept in plastic cups that were placed under a heat lamp. Each condition was monitored over a four-day period to ensure the temperatures were constant. Following the four days, the spider contraptions were weighed to get final measurements of the spider web densities.
