In this video I will show you how to make a green flame, and also the difference between boric acid and borax. Please comment and subscribe for more kitchen chemistry and backyard science!

Copper chloride acts as a catalyst decomposing the hydrogen peroxide. May also form copper oxychloride copper I oxide, and copper I chloride

Hydrogen peroxide acts as a catalyst oxidizing the copper. This is a very exothermic reaction and it can easily boil over if you don't keep an eye on it.

A very very very saturated solution. The whole solution crystallized and broke my glass! Dye from highlighter.

Creating zinc chloride, and hydrogen gas. Just a warning don't put your face close like I did! I got a couple drops of hydrochloric acid on my face from the bubbles. I was wearing glasses but scary.

DIY chloroform, an easy preparation! watch my other video on how to synthesize it. Just a video showing the amount of chloroform i made, i was only using a 2.5 percent concentration of sodium hypochlorite that's why the yield is low. You can see bubbles of co2 from phosgene degrade.

Yes it hurts..

Reacting copper sulphate solution with ammonia hydroxide. If you do not want copper hydroxide use an excess of ammonia.

It failed because the bottle was clear and the wine was light color they had no chance to absorb energy from the Sun.

Just produces O2, Cl2, and HCl gasses. A lot of it. I only used 5 grams TCCA.

Ghetto style. 2 gallons 10% sodium hypochlorate and 156ml acetone. Phosgene will not be a problem if you stabilize with a layer of water. Decomposes into CO2.

Easy DIY lamp! Hack an old lightbulb into a alcohol lamp with a green flame with only denatured alcohol and boric acid! This was my very first video! Id like to thank a few of my followers (and fellow scientists!) for encouraging me with positive feedback in the beginning. Gooferking Science, ChemCamTV, Toothpick999, coolwierdgreat, antiswattt3, AMchemistry, Finnnicus, and Paul Pyro. Your comments encouraged me to keep going :) wow 2000 views on this video 6 months later, i never would have th

In this video I am distilling the chloroform I made in a earlier video

Please read the entire description! 50gm ASA 33.5gm NaOH 150ml water Filter Add conc. HCl to taste (~150ml) Filter Wash, rinse & repeat. Dry 2 things 1.) You don't need to separate the ASA from tablets. 2.) Stir NaOH slowly! (a) CH3COO-C6H4-COOH + NaOH → CH3COO-C6H4-COONa + H2O (b) CH3COO-C6H4-COONa + NaOH → HO-C6H4-COONa + CH3COONa (c) HO-C6H4-COONa + NaOH → NaO-C6H4-COONa + H2O (d) NaO-C6H4-COONa + 2 HCl → HO-C6H4-COOH + 2 NaCl

Recrystallize in enough methanol to dissolve, then place in refrigerator for large crystals (4 days) OR freezer for smaller (4-8 hours). do multiple smaller pulls. 90ml acetone 10ml chloroform 1-2gm NaOH Yield~ 4gm Please note this is not safe for consumption. It may contain small amounts of un reacted chemicals or many possible side products.

Saw another user with this design, my Sister and I tried it out this afternoon. It's not perfect, and the flame circulation could be improved, but it is easy to use without constant attention.

Sorry little sister! 46" Fresnel lens from rear projection tv. Total time 5 minutes.

Sorry about the audio guys, This was way back when i was making videos completely on my cellphone! I used 90% methanol 10% h20 as a solvent. That final product was 10ml of capsaicin oil, I put some on a toothpick and it burned my lips for 20 minutes D: What else can i do with this interesting piece of equipment?

In this video we make electric matches to safely detonate our experiments. You should aim for a 95-5% ratio of your propellent to nitrocellulose (pingpong balls). a pingpong ball weighs 2g, so use about 50g of powder. We used half that and it works great. The steel wool is sensitive enough to glow red hot through 100ft of wire with a battery.

We made a cannon that fires water bottles. Why you ask? Why not!?! Using 1-2 ounces of blackpowder, and 10-16oz of water. If we filled the bottles up all the way they exploded :/

This is our first attempt at exploding arrows, we probably used a half ounce of black powder in the arrow itself. It was a carbon arrow. We removed the tip and replaced it with a large shotgun primer. I saw these first in the anarchists cookbook about 15 years ago. The bang was rather satisfying.. probably doing it again soon!

This cannon was pretty extreme. It shot a golf ball at speeds approaching the speed of sound and has some SERIOUS power. We typically used around 1 ounce of powder charge, enough to propel the ball clear through a bucket, and into the dirt. Electrical ignition was not bothered with, used long fuses instead. Your right Chemcam, it is a PITA :P

lightbulb at 20'' 700w magnatron I will upload a video once I have enough gadgets to fry!

Easy DIY chemistry project, great for science fairs because its a great demonstration! This is great for the chemistry beginner. I used 150ml of a 10% ammonia solution and 50ml of 30% HCl After they reacted, i boiled it down, and dried it in the oven. It tastes very salty/tart!

I made a mistake. Schweizer's reagent is produced by copper hydroxide, then a excess of ammonia. not just coppersulfate with ammonia, thats just Tetramminecopper(II) sulfate. oops :)

Copper Catalytic Cyrolysis of Acetone, Methyl Ethyl Ketone (MEK), Ethanol, Methanol. Catalyst.

Hey guys, in this video I show you how I built my microwave gun, also known as a HERF gun. I take a magnetron out of the oven and connect it to a waveguide. The results were more than I expected! FIRST- Microwaves are not "dangerous". They do not have enough energy to damage DNA and cause cancer. The only risk is thermal burns, which are unlikely because you are 70% water and have a high heat capacity. Cataracts may happen if you stare into the beam, and there is a good chance you will fry your

For more information and reaction mechanisms, look at the link below. www.sciencemadness.org/talk/files.php?pid=75149&aid=1734‎ PEG is chosen as a hydraulic brake fluid for its very high boiling point. Usually over 400f. So this is a very exothermic reaction! Something I noticed. If the hypochlorite or brake fluid contains an appreciable amount of water you will not get a fire, instead you will get a very thick white smoke that is probably toxic.

nitrites AKA "Poppers" are extremely flammable liquids. Synthesis next week

Microwave oven transformer

Today im demonstrating the Synthesis of Benzocaine! Watch until the end for a chance to win some Benzocaine!! I used 150ml EtOH 15gm PABA 6ml Sulfuric acid

And now for a break in our scheduled programming.. just had to share too fun!

Enjoy! Question, comments? So i was wrong on my math. 6grams to 4grams is wrong and im stupid ;) HClO3 pointed out that the correct stochiometry would be 68g ammonia with 180g of formaldehyde.

In this video i salvage an old photo copier for some interesting parts. Their is a nice high voltage transformer, I will be using the high voltage supply for my Marx generator in an upcoming video. I also got some nice mirrors, and a nice macro-lens for my cellphone.

I show how to make the marquis reagent from formaldehyde and sulfuric acid, and preform tests on modifinil, promethazine, tizanidine, ritilin (methylphenidate), acetominiphen, and aspirin.

Using a 200w induction heater to heat a bolt, then dropping it into liquid nitrogen. The liquid nitrogen starts leaking and science quickly devolves into shenanigans :)

Used my angle grinder, and my new dremel to make a knife. sorry its been awhile, and sorry if i miss your comments!
