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)
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)
a lamp (halogen is best, but you can use any other, but it has to heat a lot)
a switch
a plug

Step 1: preparing the bottle

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.

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.

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.

put the cap on the bottle
<p>is there any other things that can use to coloring the alcohol beside felter pen?<br>and what percentage of alcohol did you use?<br>very great instruction anyway~ :))</p>
<p>how much alcohol and oil do you add?</p>
<p>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.</p>
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: <br>http://www.instructables.com/id/DIY-lava-lamp/
Thanks very much tgferreira184.
Needs a Nuka-Cola Quantum sticker : )
nao ha ca disso
What kind of alcohol did you use? Isopropyl or Ethyl?
Ethyl, but if Isopropyl has the same purity, it should work too, becouse we are going to dissolve some water in it.
Very nice job, you should be proud of the instructable and the project.
Awesome! I used to have a lava lamp. It would be fun to create my own :)
I'm sorry if my English is bad, but I'm from Portugal nd I have to learn portuguese, english and french all at once, so, it's very difficult to learn english and french together, among the other subjects
tgferreira184 - ignore the rude comments....your instructable was awesome! :^D What I love most is that you researched this and wanted something 'different' - meaning without the use of alkaseltzer! Well done!! <br> <br>As for the spelling/grammar/English -- I know many, many people -- of older generations that can't spell or write worth beans! <br> <br>Again - as for the submission - WELL done! That's what it was for -- I'm sure you wanted us to learn how to create our own Lava Lamps -- not to discuss how well or not well you spell, right?
To: Lithium Rain. <br> <br>I only speak/read English and did not have any problem following this project. Better an interesting project with poorish english than none at all. I wonder if you can write as well as tgferreira in his language and at his age? (By the way 'apalled' is spelt 'appalled') <br>
Great! <br>Ferreira is a common surname in Brazil or Portugal. Being a school project, his age is, at maximum, 16yo. <br>My native language is Portuguese and I made some mistakes in English, sometimes. I don&Acirc;&acute;t know all the grammatical rules but I decided to learn English till I can get or pass a required information. <br>I&Acirc;&acute;d like to suggest the people who are annoyed about this poor English, to waste some time &quot;fixing&quot; the text and send it back to the author in order he/she can publish it again. <br>Another option, everybody should write an Instructable in his current language. It would be a collection of photos for most of people who speaks only English. <br>
thanks for comprehension
I agree. Well said.
Take a look at the cord end and you will see that it's not a USA type plug. So I would say english is not his first language. Dam grammer nazis.
Step 1 Part 2 : preparing the lava <br> <br>Instead of that slow, and difficult way... Try adding 1 part beeswax, 3 part crayon, and 3-5 part oil. Place them all in a heat proof bowl, and set in a pan. Fill pan with water about halfway up the side of the bowl(and keep the water topped off as you go). Now just apply heat, till everything begins melting together, and stir well. <br> <br>Let it cool, and check for consistency. Should be something like marshmallow. <br>If it's too hard, add more oil, reheat, and remix. <br>Either pour into your lavalamp while still warm, or wait till it cools, and cut into pieces that will fit through the neck. <br> <br>The ratio of the different types of oil and wax will GREATLY effect the action of the lava. Trial and error are the only way to get it &quot;just right&quot;. <br>It will probably never be as smooth as the brand name lava. then again, there's no Carbon tetrachloride to toxify your liver either ;-) <br>
I have been 1 week trying to find instructions to this, but most of them used alka-seltzer, so, I didn't had many options to choose, becouse they were all like this or with alka-seltzer. anyway, this was a school project, o proof of concept. maybe, I do another and use your instructions. anyway, thanks for the comment, it will probably help other people.
There's a really good recipe out there for an actual lavalamp that will work just the same as original lavalamps. <br> <br>You will need something to measure specific gravity... I keep saltwater fish tanks, so I have a refractometer handy. <br> <br>But... <br> <br>. Paraffin Wax <br>. Automotive brake cleaner (that is --non-flammable-- and contains tetrachloroethylene) or PERC (used by dry cleaners) <br>. Salt (either pickling salt or I used epsom salt) <br>. Distilled Water <br>. Dishwashing liquid <br>. (optional'sh) Antifreeze <br> <br>You can see by the list of material needed that it's not something you should take lightly... there is some really toxic stuff in there. <br> <br>Get two cups/bowls and fill them with water. Now add some salt to each of them. You want 1 to have a specific gravity of 1.02, and the other to be 1.04. This is for testing the wax from the next step. <br> <br>Melt about a cup of wax in a double boiler (never, never melt wax in a pot/pan that is in direct contact with the burner. Ever. Don't do it.), after it's melted add in 1/3 cup of the brake cleaner or perc. Mix it well. <br> <br>Take a little bit of the wax/perc mixture and drop it into the cup/bowl that has the 1.02 water/salt mix in it... it should sink. If it doesn't sink, add a little more perc to the wax and then try it again. You want to get it to where it just sinks in the 1.02 water. <br> <br>Now, take a drop of the wax and put it in the 1.04 water/salt mix. It should float. <br> <br>If it sinks in the 1.02, but floats in the 1.04... then your wax is around 1.03, right about where you want it. <br> <br>Take that cup of wax (this is meant for larger bottles... stuff that is the same size as a normal lavalamp) and pour it into the bottle so that it sits on the bottom. Let the wax cool. <br> <br>There's your lava. <br> <br>Now fill the bottle up with distill water, to where there's about 2-3 inches left at the top. <br> <br>Add in a couple of teaspoons of salt and shake it up for the salt to completely dissolve. <br> <br>Now turn on the lamp and let everything heat up. The lava will still sit at the bottom of the bottle. <br> <br>Mix up, in a separate bowl/glass a super-saturated solution of distilled water and the salt. Get as much salt dissolved in there as possible. Remember to heat it up so you can get as much salt in there as possible. <br> <br>Now, a teaspoon or so at a time (a dropper works really good for this) add that super-saturated solution of saltwater into the lamp. Go slowly. As you add it you'll start to see the lava try to rise. Go slowly. Add a little more. Go slowly. Just to where the lava starts to actually leave the bottom of the bottle. Go slowly (keep saying that because it's important). Eventually the lava will leave the bottom of the bottle, float to the top, and fall back down. ... <br> <br>You now have a lava lamp. <br> <br>Now you can tinker with it a little... remember that dishsoap and optional antifreeze from before? Well, you use that to adjust how the lava flows. Add a small (SMALL) drop of the dishsoap to the lavalamp and that will make the lava a bit more &quot;runny&quot; so it will look like normal lava lamps. A drop or two of the antifreeze will pretty much do the same thing. <br> <br>There is 1 other piece that's needed'sh... and that's a coil of some sort... you can see them in the bottom of normal lavalamps. They're there to give the lava something to hold on to on the bottom of the bottle and keep it buldging in the middle instead of just trying to ride up the glass. <br> <br>Also, the bottle you turn into a lavalamp has to be SUPER clean inside... if there's anything on the glass (soap residue, wax residue, etc) the lava will stick to it and just end up looking nasty. <br> <br>So, those last two bits are up to you... but there you go... how to make a real lava lamp.
