På
http://www.psychicgoldfish.com/sub_page/whatido/lavalamp.htm skrives der
følgende:
a.. If you try the rubbing alcohol/mineral oil mixture, try living with the
clear oil and alcohol before you rush out and dye it. In spite of what the
webpage above says, anything you add to one seems to eventually bleed into
the other, leading to the whole thing being dyed a uniform color. Maybe I
just had bad luck in my tests and materials. But at least try a test case
before you dump a bunch of dyes and paints into your carefully balanced lava
lamp. And the clear oil looks like liquid glass as it catches the light,
which is just cool.
Så udfra det går jeg ligesom ud fra at der er noget om snakken men hvis du
mener du har et bud på en farve der ikke vil flyde ud med tiden så har det
da selvfølgeligt interesse.
Jeg har dog tænkt mig at lave en prøve hvor jeg vil tilsætte farve og så
lade det stå i et par måneder og se hvad der sker!!
