# 1.Geyser - Waimea Physics

1.Geyser HOLLY STURROCK WAIMEA COLLEGE The Problem Support a long, vertical tube containing water. Heat the tube directly from the bottom and you will observe that the water erupts. Arrange for the water to drain back into the tube to allow repeated eruptions. Investigate the parameters that affect the time dependence of the process. 2 Overview Experimental Set-Up
