i bought a lava lamp, so called, today from B and M for 8 quid. it is a lava lamp, it looks great. i love it! it is from the same place as me, the 1970s. but it isn't made by Matmos? it should have been 16 quid but box was crushed and it was the last on the shelf. annoyingly the cool purple colour comes, in part at least, from a layer applied to the glass. i can see a few dots where the dye didnt quite stick to it. but the way they finely adjudged the relative densities is awesome. i been watching it for an hour. the times it makes a blob, rises, but the blob half fails, so half falls back to the bottom, so it looks great is remarkable. my neighbour had one when i was about 8. it was nowhere near as good as this one, the goo used to stick to the top. it is made by "glow", i suppose matmos lost the rights sometime in the last 40 years? matmos? is that not a dr who baddie?....off to look online...... yep, that was quite interesting. it seems the original 'lava lamps' were in fact called 'astro lamps' by their creator, matmos. so anyone can make a thing called a lava lamp. i live and learn! i just read the box, it says non-toxic so i might unscrew it and have a little taste of a finger-tips worth... i did. yuk! soapy and oily, but mineral oily not cooking oily. bleeurhg. - extra addendum, i recalled correctly, you will be pleased to learn. matmos was a pulsating,glowing alien brain thing from dr who.. so apposite name for the lamps..........i have noticed some wax sticks to the top, only a little bit, but it gets hung up on the meniscus, it it probably useful as it seems to bounce off rising blobs more readily than otherwise. but why didnt they fill the whole bottle with fluid? was this bit planned? if i shake the glass enclosure this bit breaks up and buggers off, but 20 mins later another one is there. it really looks amazing, like sid barrets dreams, one imagines, for 8 quid!

My guesses to solve the corrosion issue: Nitrates are good oxidisers so that could be the culprit. It could also be the case that having an acidic pH facilitates breakdown. I would try making a tiny adjustment to the pH using a buffer, and if that fails then trying some metal corrosion inhibitors like sodium metabisulfite (used in winemaking).

[@jounik]

The pH of a 45% calcium nitrate solution is 6.5, so it is slightly acidic. Maybe bumping that to 7 by a small amount of AlOH would work, since it would also preload the aluminum ion concentration in the solution.

I'm cautious about mixing random chemicals in glass bottles. But the PH idea is interesting.

I had a look at possible alternatives for calcium nitrate, mainly looking at the solubility in water. Obviously I tried to ignore anything which might be particularly harmful or difficult to get in terms of availability or price. I came up with 2. Copper nitrate which has a similar solubility to calcium nitrate and will give a nice blue colour and potassium thiocyanate which has a higher solubility. Both are readily available on eBay. A cheaper alternative might be fructose which is extremely soluble but I'm not certain it would not be compromised by bacteria and molds.

I always wondered what would happen to Glitter lamps and Lava lamps when Tungsten globes become unobtanium. Looks like this is a nice project. Could you use a couple of resistors glued to the base to heat the liquid? I would think if the LED was slightly underrun, it should last pretty well forever so the lamp would never need to be pulled apart.

[@marcogenovesi8570]

yes resistors are the "quick way" to convert an old glitter lamp but you need high power resistors as you are now replacing a 20-25w lamp with a 2-5w led. If you make a new one from scratch it's better to alter the liquid like Clive is doing so it works with the much less power hunry leds. Also the 3D printed case will be weakened or even melt with a 20w heating element inside like a tungsten lamp or the resistors

Interesting thing about that calcium fertilizer. If it were pure Ca(NO3)2, it'd have 17% nitrogen and 24.3% calcium as far as molecular mass is concerned. It seems like there's some other calcium salt mixed into the fertilizer, lowering the nitrate anion to calcium cation concentration ratio.

Dad promptly exploded (pun intended) and carefully explained that there's a reason why you can make bombs from fertiliser... And what do you think happens when your poisons store is on top on about the same amount of explosives as can be found in the magazines of the entire King George V class (1939) of battleship... For those who haven't seen it yet.. Everything was *carefully* moved out of the 1st floor poisons store, and all the fertiliser was moved *extremely carefully* to the 1st floor, and all the poisons were put on the ground floor.

hey Clive, you might wanna check out the Rainbow Motion Glitter Lamp, by Art + Sound, too. It has three multi-colour LEDs to illuminate the lamp, plus a small dc motor with a neodymium magnet attached to the end of the shaft. The motor-mounted magnet magnetically couples to another magnet attached to an impeller inside, at the bottom of the glitter lamp. So the only contact between the base and the lamp is the magnetic coupling between the motor shaft, in the base, and the impeller, inside the lamp. The rotating impeller swirls the liquid and glitter around. It’s clever and simple. oh and the lamp is very low power, consuming less than 100mA.

One goes to the Common terminal and the other goes to either of the two other terminals on a 2-way switch. The order doesn't matter. If the old switch has three current-carrying wires, then it is one that needs a neutral connected (white in the US). If the new one has a terminal for neutral, put it there. If it doesn't, then just cap and tape that wire and push it into the box. If the new switch needs a neutral but the old one didn't, then you're going to need to have someone who knows how to do it see if a neutral is present, and if not, how to get one there.

My first thought for an alternative to the calcium nitrate was propylene glycol--it's much (4x) more viscous than water--but then I looked up the density and found that it's only a few percent greater than pure water. Then I considered a sugar solution, but at ambient temperatures, even though you can dissolve more than a 2 grams of sugar per gram of water, the solution ends up with a specific gravity of ~1.4 as compared to the 2.5 you get with the calcium salt (due to the salt's greater density). It may be interesting to experiment with adding propylene glycol to see how it affects the flow. Incidentally, if you add propylene glycol to the soap solution children use to blow bubbles, the bubbles will last longer.

[@bigclivedotcom]

I tried many glycols and glycerin, but the glitter still settles out at the bottom.

@@bigclivedotcom w a mirror for a wall hanging or clear for a dynamic stained glass effect! nice … they'll sell like hotcakes!

[@PhilXavierSierraJones]

Off-topic but what happened to your left middle finger?

[@bigclivedotcom]

Winter wear and tear. Cracked skin on the knuckle.

[@manuellongo4365]

Cute, interesting project and can justify that (rather expensive) 3D printer by making something for the house 😁

[@kareemtawab]

That's true genius!

[@DerMarkus1982]

Ouch! What happened to your left middle finger's outermost joint? Some tool seems to have bitten off a piece of flesh and skin from there. I hope you recover from that injury quickly! 😉

[@bigclivedotcom]

Just winter wear and tear.

Great project....as a person who has a Chemistry degree....Calcium Nitrate is CaNO3.....the CaN label on your bottle made my labeling mind upset! LOL

[@bigclivedotcom]

It was more of a rough reminder of what was in the bottle.

Brilliant Clive love it thanks

Nice project. Not sure whether I ever will try to do it, but it is nice to know how to do something like that. It is still tempting to modify my old lava lamp, though. The SCAD file, though, could have some improvement in the header section, like the comments of the parameters above and not on the same line. On the same line you could add a restriction for the slider in the customizer like // The height for the foot height = 20 // [20:1:200]; This you get a slider in the customizer which goes from 20 to 200 with 1 resolution. For a list of options like the quality you could use //[40,70,100] The comment on top will show as header for the parameter. You can make sections for the customizer by putting something like /* [Optional parameters] */ as header where the section for optional parameters will begin. This creates a header that folds out the parameter section when you click on it. The take over of variables stops at the first defined module, by the way. It is easy to define a dummy module just for this case that is defined just below the customizable variables. There is no need if you don't define another variable later, though. I personally like to ask the system variable $preview whether we are in preview mode, making the basic configuration faster by manipulating $fn. This can be done by $fn = $preview ? 45 : 100; This switches the sections from 45 in preview mode (F5) to 100 in rendered mode (F6) automatically.

Hi Clive, great video. Could you use cooking oil as a liquid base as it’s denser than water? BTW really like your zoom box!

[@chrishartley1210]

It isn't denser than water, just more viscous. It will float on water.

[@lmwlmw4468]

Nice work.

[@phonotical]

Must have a flared base.....

[@Merfnad]

I always pronunce it open-scad as well.

[@Taco_Syndicate]

Could the secret ingredient be dish soap?

[@bigclivedotcom]

I wish it was that easy.

[@Lumibear.]

Intriguing! Nice effect.

[@tmanimal]

Makes a change from stuffing a resistor & a bulb in the base... Incident, I couldn't help but notice News reports about a 'New' technology allowing domestic heating by means of wall mounted, powered carbon fiber sheeting, virtually just putting a big, flat, carbon resistor, under your wallpaper.. Any comments ????

[@bigclivedotcom]

The Russians have been using carbon fibre panels laminated into wall hanging decoration for a long time. The idea of putting it under wallpaper is probably from the same bad idea department as the people who proposed electroluminescent wallpaper for lighting. Usually freshly qualified "design students" with no grasp of reality.

Our glitter lamp is in a cupboard some where so may be I could get it out and change it over to a LED lamp

[@aristocrat_000G]

sparkly!~

[@laurao2107]

I got one but 😢I thought it also had bubbles, so sad

[@U014B]

4:23 This is exactly how I feel about Worrkestersheer sauce.
