Watching the mesmerizing movements of a lava lamp is always a fun time. The science behind it is even more fascinating. The wax has a density slightly more than the surrounding water, so it remains on the bottom. As it heats up it expands, decreases enough in density to be lighter than the water and rises. As it rises it cools and contracts enough to be more dense than and then sink, repeating the cycle.
This unit is made from all scientific labware. A flask stand and Buchner funnel and make up the base and a support stand and clamp holds a flat bottom boiling flask. The unit has an inline dimmer switch in case the unit is getting over heated. The cord is 6 foot long. This unit uses a 40 Watt bulb and take about ~2 hours to heat up properly. Do not run for more than 9 hours at a time.
14" tall with a base of 6" X 8"
*Warning: the unit gets very hot, do not touch when on. Do not shake the lava lamp.*
