Introduction: DIY Lava Lamp Without Alka-seltzer

in my school project I decided to make a lava lamp, becouse I wanted one.
I made a little research and almost all used alka-seltzer and could be only used one time, beiing necessary to put more alka-seltzer to make it run again.
all you need is:
a small alluminium can,
a piece of net,
a pice of MDF,
a glass bottle (colorless is the best)
alcohol,
a felter pen (to paint alcohol)
mineral oil (is the best becouse you can paint it, but you can use olive oil, cooking oil, or similar, but you won't be able to paint it)
a crayon (to paint oil)
water
a lamp (halogen is best, but you can use any other, but it has to heat a lot)
a ceramic lamp socket (IS VERY IMPORT THAT THE LAMP SOCKET IS CERAMIC, OTHERWISE IT WILL MELT!!!!!!!!!!!!!!)
a switch
wire
a plug

Step 1: Preparing the Bottle

PART 1
preparing the alcohol
to paint the alcohol, disassemble the pen (mine was green to put the alcohol green), remove the charge and squeze the ink onto the alcohol. if necessary shake it.

PART 2
preparing the lava
to paint the lava (oil) use a crayon and dissolve it onto the oil. this is a very difficult thing, becouse you have to wet your fingers in the oil, rub them in the crayon and clean the oil in your fingers in the remaining oil.

PART3
filling the bottle
put the oil in the bottle and almost fill the bottle using the alcohol, on the remaining space go adding water until the oil almost start going up. THIS IS A VERY HARD TASK, BUT IF NOT WELL DONE THE LAMP WON'T WORK! the alcohol wil get turbid, but after some time it wiil get the original colour. if the oil goes up, put some alcohol.

PART4
put the cap on the bottle

Step 2: Doing the Electrics

wire the plu into the switch and the switch into the lamp socket and put the lamp on the lamp socket

Step 3: Preparing the Can

cut a hole in the top of the can smaller than the bottle,
cut the net and cover the hole,
cut a circle in MDF the size of the lid and glue the lamp socket on it
cut a small hole in the bottom of the can to pass the wire

Step 4: Assembling

put the can on the MDF circle and the bottle on the can and if you've done it right it will work as a lava lamp

is there any other things that can use to coloring the alcohol beside felter pen?
and what percentage of alcohol did you use?
very great instruction anyway~ :))

how much alcohol and oil do you add?

The oil is going to be the lava, so, add as much as you want, about 1/6 of the bottle was enough for me. The alcohol is to fill the rest of the bottle.

Thank you tgferreira184, this was a very good instructable and i had no problem reading the directions. Does anyone have more information on exactly how much water i should put in and the ratio of oil to alcohol?

One more question. Does this lava lamp method work on a larger scale like a vodka bottle. like this http://matej.en.ecplaza.net/3.jpg

my friend made one like mine, but with a 750ml bottle and it works too, but takes more time heating up. link:
