That pretty cool and it good that you warn others about the compressed air at 200 psi blowing up risk. Safety so you are not liable is key.

Fairly good safety feature. Well know your surrounding and never touch wires when on and never do it when your tired.

Making potassium bisuth iodide to the culture may cause it to grow faster. Here a video on how to make it. I mixed bisuth oxide with dilute HCl and Potassium iodide with KOH.

To make this process better the ratio of Lye and Knmo4 must be high but KmnO4 must be higher. First put the brand new plate of steel into cold water wash then put in with the Hot lye KmnO4 solution. Let it sit for 2 hrs. Wash it off and make Hot water with HCl bath. If done properly you should see a tint of black over the steel that the plating inverse effect on the metal. With gloves remove the plate and put it into the bath and stirr continously you should see different platterns occuring by now -- if done correctly. It a tricky process.

Well, I have a webcam and tried it got nothing even tho I am using Uranium ore which emits gamma, alpha, etc. I have it in syrofoam case and it emitting 6 uS an Hr and 900 counts per minute. Ave 386 yikes.

Cool use of a red bull. Do you think you could control it by remote?

Did this a lot in Waste water mangament and Biotech.

It seems quite complex but I like it. You know if your lucky on Amazon you can get a 2000x focal microscope normally 1500 dollars for 250 or so.

On sale from Boreal, I got a 200 dollar digital still working microscope and it normally 750. It took longer and they charged fully when it was on sale. Prolab sell them as well as staining supplies. https://prolabscientific.com/

Yes, I did one for home growing isolated bacteria from Soil.https://www.instructables.com/id/Testing-for-Microbes-in-Soil-Sterilized-Friendly-T/

I made a simple LED strobe light not as complex but with a 555 timer.

I am wondering what made this Instructable not that desirable it how to dye clothes. Yes it complex but interesting method. If only you would find a way of completely water proofing it then it would be awesome. https://www.instructables.com/id/Making-Waterproof-UV-Clothes-and-Pigment-Clothes-a/

Anyone thought of dye lasing with prisms and dyes. Maybe a Nitrogen laser. I plan to buy a expensive 200 mw 405 nm laser that fluoresces a lot of things. Most can be found on eBay.

I have an Update here is are UV dyes water soluble fluorensce types that can cost 40-50 dollars CAN but 7 dyes for 30 ml approx may work for small volumes.

Well this is a really cool Project. Here were you can find those dyes on Ebay similar to that store but can be bought nearly worldwide.https://www.ebay.ca/itm/390812242302

Hmm, this would work maybe better with glow in the UV and dark powder. Powder that attached to glue may work too.

Sodium dichromate recommended over Potassium dichromate due to solubility in water, etc can be easily bought 200 g for 20 dollars US. Keep in mind some countries may not be able to buy it --- dangerous product. Even if stored from 1990 from Russia it does not degrade in storage so that not an issue. Magnesium sulfate can be bought at any Pharmacy.

Expensive things it cool you can make them if you wanted to.

Sounds like a really cool idea. Really like it too.

I recommend pure cobalt chloride over cobalt carbonate and Hydrochloric acid. You may need to search a lab science supplier that sells to indviudals tho.

Try images again. I am assuming the bacteria made this sample basic due to Urea but I will test it with pH paper.

pH of 9 indicating Urea and Protien were converted into NH3 which some got trapped in the water.

Images...

Here the Urea-Protein mix without air as a next sample. Biofilm and a yellow color has occured.

Most likely a wrong type of cry a toxin. One that does not affect ants nor fruitflies. It may notbe practical if it worked tho. You would need to perserve the culture in freezer or add preseratives against mold.

1 ml sample had approx 1 million so 30 percent of that was the toxin at 300,000 spore toxins molecules present.

Very cool concept but cannot you buy them glass ones for 10 dollars on Ebay? I find this method if you don't know what exactly your doing to be dangerous. Still as a concept it very cool.

Here some other results with Prisms too. It an Interesting Idea to use them. The lasers shine and give unqiue optics with a CD case and a Prism. I may buy more lasers at different colors too.

Has anyone thought of using carefully the dye 5-SSA with iron chloride and ethanol and methanol or acetone or even ethanol? I did this with paper it not similar but works very well maybe with controlled setting and fabric (the lye) did not eat the fabric dipped on paper it may work.5-SSA is 5-Sulfosalicylic acid. Alc as a dye or acetone that make it polar works. Acids turn it red depending on many factors including use HCl, etc with the dye. Plus 50 g cost 10 dollars on Ebay cheaply 98 percent.I am really glad i discovered it.

Hey that a very cool video. I just loved the candle part.

If you send CO2 gas or carefully burned vapours of ethanol could they be affected by a spark gap like this. Your project is very impressive and used to clean up dirty air from coal plants, etc.Heard of it before but did not know a lot about it. Good instructable thanks!

By directing air at a Jacob ladder I can affect how quickly it jumps up and down the copper poles. By a fan.

Instructables should pin this to get you more views. Man such a cool project and only 44 views! Yes I do cool projects and don't know why i get low views here too.

Well it could be dependant on dose and resitance to the Oil may occur over a long period of time (limitation of natural stuff) too. It may harm bees but unlikely.nitially found to be active as a feeding inhibitor towards the desert locust (Schistocerca gregaria),[3] it is now known to affect over 200 species of insects, by acting mainly as an antifeedant and growth disruptor. It was recently found that azadirachitin possesses considerable toxicity towards African cotton leafworm (Spodoptera littarolis), which are resistant to a commonly used biological pesticide, Bacillus thuringiensis. Azadirachtin fulfills many of the criteria needed for a good insecticide. Azadirachtin is biodegradable (it degrades within 100 hours when exposed to light and water) and shows very low toxicity to mamma...

Azadirachtin fulfills many of the criteria needed for a good insecticide. Azadirachtin is biodegradable (it degrades within 100 hours when exposed to light and water) and shows very low toxicity to mammals (the LD50 in rats is > 3,540 mg/kg making it practically non-toxic).This compound is found in the seeds (0.2 to 0.8 percent by weight) of the neem tree, Azadirachta indica (hence the prefix aza does not imply an aza compound, but refers to the scientific species name). Many more compounds, related to azadirachtin, are present in the seeds as well as in the leaves and the bark of the neem tree which also show strong biological activities among various pest insects [4][5] Effects of these preparations on beneficial arthropods are generally considered to be minimal. Some laboratory and field studies have found neem extracts to be compatible with biological control. Because pure neem oil contains other insecticidal and fungicidal compounds in addition to azadirachtin, it is generally mixed at a rate of 1 ounce per gallon (7.8 ml/l) of water when used as a pesticide.

That a wiki quote apparently it a mild neutrotoxin with a high LD50 for humans and pets.

This is a way to Neutralize the dye. Very important.

Adding acid to the dye then adding baking soda until it fizzes and stops then add bleach this converts the dye into something non reactive even in acid or base. Tried it.

Some more art with dyes with Paper. Enjoy. :)

Structure of the dye plus a Cl- times 3 not shown in the 5-SSA.

Here is the same 5-SSA with Iron chloride.pH 7 = Purple.pH 14 Orange-brown.Ph 0 Red orange.

I am wondering compaired to a AM radio with two transistors plus an Speaker amplifier - Amp Op type circuit is this Tube radio equally powerful as One transistor radio with ear piece or are their some gain issues here? Nice Project. Cool :)

Yeah to anyone concern this isn't a GMO project. You would need a permit to do that. This is using a plant hormone to encourage plants to grow. Salicylic acid is a hormone that encourages the plant immune system. I am not sure but salts of it may help if done properly with other hormones cause the growth of plants and build immune systems of the plant.I wanted to do plant pathogens on plants with SA or a Sodium sulfosalicylic acid salt but some of these pathogens like Penicliium are difficult to control and others (Well I don't want to harvist them). Also you would need a microbe incubator for that -- expensive. Good Instructable. :) Learned something new here.

Just Look at the Second Secret of Mana game SD3. It only available for Japan and can only be played as an Emulator. If it wasn't for emulation this masterpiece would have never seen the day outside of Japan. Why did they release it outside of Japan? Big mystery too. I did not like Secret of mana max 4 items and the slow hit rate. But SD 3 is underestimated. I would have never got a PS3 if not for emulation and final fantasy games. :) https://www.youtube.com/watch?v=MXZVa5r5lYs

Certain washers can be heated on a pan and coated with iron and acid (HCl) then air dried and soaked in copper sulfate sol (5 g in 250 ml) for 15-20 minutes. Many factors like the metal results in these unique patterns. Chain mail when I am done will be used to make art. That the bigger Plan.

Interesting, despite the danger. Neutrons, Protons in advance fusion reactors can be used to make New isotopes for Medicine just like Particle accelerators converting Uranium 235 into technium 99 for PET scans, etc.

How is this different than a normal spectrometer? Well I am VERY impressed with this! To build an Polarimeter takes a Lot of skill. Good Job!

Yeah, Silicone does work but If you want to dye fabric I found special Scotch guard silicone spray works for many dyes including glow UV dye. A spray even tho more expensive can coat thinly dyes that I have made too. Here the Instructable I made. Silicone alone in mineral spirits gave me trouble. So I recommend a spray. https://www.instructables.com/id/Making-Waterproof-UV-Clothes-and-Pigment-Clothes-a/

Yes it done incorrectly it very dangerous. Just like Shock therapy it has medical applicaitons in treating Bipolar, depression (Resistant) without as many harsh side effects like temp memory loss from ECT. Good work tho.

Had a friend who went through tDCS which the docs in Canada said it safer and more effective than ECT. It pulled him out of his disorder like Catania. Like Severe Bipolar, Depression when used properly or as a last resort it still controversial it can save a life.

Yeah that quite fast 9200 RPM. Mine are 2 ml times 8 constant 7000 RPM and 1000-4000 20 ml tubes but I don't go past 3000 RPM since it shakes a lot. Something to consider Proper shielding incase that rotar breaks. Very cool and I enjoyed seeing this Instructable.

Yeah, the color change is due to cystals of oxides of copper, iron and zinc (Bronze), It is a thin film interference. I made this instructable since their was no one like it on Instructable.

I want to do this with copper pipes know it will work since it copper but I can find Thiourea dioxide which 500 g cost 40 dollars CAN and Thiourea alone is 70-80 dollars alone for 30 g.Would thiourea dioxide work instead?Thiourea dioxide + water >>>>> Thiourea + Hydrogen peroxide.Tin (II) chloride plus H202 should give Tin (IV) chloride and tin hydrooxychloride.6 SnCl2 (aq) + O2 (g) + 2 H2O (l) → 2 SnCl4 (aq) + 4 Sn(OH)Cl (s).However in excess Hydrochloric acid oxygen from the Hydrogen peroxide and some chlorine gas will be emitted. 2HCl + H202 >>> 2H20 + Cl2.I am not entirely sure but would chlorine negatively effect the plating due to its reactivity?Most likely tin chloride (IV) would reverse back to tin (II) chloride and have little effect.

It an interesting concept. BTW it would NOT be recommended probably for Bipolar or people very sensitive to sleep. It because lack of sleep can trigger Mania and other symptoms like Psychosis in Bipolar. I could see this if done properly treat mild to moderate depression and it may reduce symptoms of severe depression but that ALWAYS requires antidepressant as a treatment too.I know a friend with Bi and if he overexposed to blue screen at the TV, videogames or computer it makes his Mania worse.It not for everbody tho.

Although my incubator isn't as complex it uses a thermometer one outside and one inside. I am using it to grow broths of bacillus L bacteria that produce a NATURAL selective insecticide. A 20W CFL does not release enough IR heat to raise the temp to 25-35 degrees C. Ideal for these bacteria.

Do you know what the acetic acid does to the glycerin and the starch? I assume it helps produce glucose polymers that may link to each other. Is it possible to use dyes that glow under UV or would they be effected by acetic acid. I know a solution of sodium fluorescien work best at pH 6-7 so having an acetic environment may prevent it from glowing under UV. Dyes like Indigo carmine, Malachite green, Safranin O, India Ink could they be used with this green plastic?
