cool little comparison i set up a while back, 1996 US lava lite on the left and 2021 UK mathmos on the right. currently torn over which one i prefer : r/Lavalamps
Mathmos Astro Copper Lava Lamp | 1960s Original Lava Lamps
Mathmos Rokit Giant Lava Lamp - Made in Britain
A Mathmos lamp next to a Lava Lite is a real life “expectations vs reality” : r/Lavalamps
