Hey speaking of Lava lamps before my job forced me to move I had one of the original Colossus lava lamps yep the one that was around 4 feet tall sold it because I did not want to chance the 300 mile trip the glass was not very thick it used a 200 watt heating lamp. Bought it for $700 sold it for $1300. This lamp was just something to see once the lava got going it took about 5 hours to heat up its been about 2 years since I sold it and its in a vape, head shop in Akron Ohio.
