this is mine, with a CD for height reference. cost me about
70dollars from a shop in heeren. the shop is opp the Wan Ton Mee
shop i think, not 77th street.
in Annex but cant remember which floor. several designs to choose,
with the wax colour and liquid colour, which for mine would be blue
wax and clear white liquid.
the bulb will blow after few months. had changed 2 bulbs and still
going strong. bulbs are at $5 each at the same shop. tried looking
for cheaper bulbs from hardware stall but they dun carry the size
of the lava lamp bulbs...
it serves as a night lamp in my room so my room wouldnt be too
dark. nowadays when i go overseas or holidays i must sleep with the
night light on. abit scared of dark now....
