There is a kit out there for this type of thing. Looks like a monkey
with his hands over his head, hanging from a horizontal string. One hand
moves above and in front of the other and the process repeats. I think,
if viewed from the side, it is a circular motion. Like what you get from
a bicycle crank, if the pedals were the hands. I think the kit is
primarily made of wood with a motor and crank. The maker may be Tamiya
out of Japan, but I know I've seen them in the USA at hobby shop.

i'd recommend - dimethylphtalate - or how is it called in
english. it is 1.19 densier than water, and it's non - corrosive, inert,
won't evaporate like alcohol and it's clear. Have no idea where to
get it from - ask your chemistry teacher.

but there has to be some sort of under pressure. When i used a
little torch and heated the bulb, the almost melted glass went into
the bulb and formed something like stalactite.

If the bulb was made in LA California and you opened it in Denver Colorado
you would find pressure! the bulbs internal pressure is not a function of
want... just cost... it if fare cheaper to make it at atmospheric
pressure... or close...

its pattern but yes it can be done without a microprossesor but a microprossesor
is easyer then the alternitives
