Rules for Posting Guides on Our Community

1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.

2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.

3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.

4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.

5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.

6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

Some will definitely try the “don’t do it”s. If that is you, please report back after your experiment… Better if you can record it.

[–] Skullgrid@lemmy.world 3 points 3 weeks ago (2 children)

Peroxide + Hair Conditioner both sounds dangerous and like it could happen by accident.

I'd recommend against washing out hairbleach with hair conditioner, but you do you....

and report back from the hospital.

[–] abbadon420@sh.itjust.works 3 points 3 weeks ago

I seriously wonder what that produces

[–] QualifiedKitten@discuss.online 2 points 3 weeks ago (1 children)

Yeah, that one really confused me because I'm almost certain that I've previously mixed some conditioner directly in my hair bleach mixture, and still have no clue what the potential problem is.

[–] Skullgrid@lemmy.world 1 points 3 weeks ago

Let's hope you don't end up in the next class action lawsuit

WTF is washing up liquid?

I'm guessing liquid dish soap.

Or Australian, if the “monash” in his username refers to the university or municipal region, rather than being the somewhat uncommon surname of the man both were named after.

You're a nationalist on a strongly socialist oriented platform. Luckily you're not German.

Oh shit, watup

WTF is liquid dish soap?

Sounds a bit like washing up liquid

[–] supergrizzlybear@pawb.social 8 points 3 weeks ago

believe it or not its liquid that you use for doing the washing up

[–] BCsven@lemmy.ca 3 points 3 weeks ago (1 children)

The weird part is they say when you add the liquid dish soap to water it makes "nothing", it should make a sudsy dish cleaning bath

[–] CubitOom 1 points 3 weeks ago

Nah...you can't washup wa'er so it's accurate.

[–] SweetCitrusBuzz@beehaw.org 2 points 3 weeks ago (1 children)
[–] CubitOom 3 points 3 weeks ago (1 children)

Never heard it called that before, guessing it's regional vernacular.

[–] JillyB@beehaw.org 6 points 3 weeks ago

It's a British thing

[–] Postmortal_Pop@lemmy.world 14 points 3 weeks ago (2 children)

Ok, wtf are the "don't do it" boxes? the serious toxic boxes explain what they do and are red. The red from the "don't do it" boxes implies that it's toxic gas bad, but I don't see why it wouldn't be labeled if that's the case

[–] Arondeus@lemmy.ca 9 points 3 weeks ago (1 children)

Hair Conditioner + Hydrogen peroxide: could potentially be used to lighten hair, but getting the concentrations right without ruining your hair and possibly damaging skin would be tough. Don't do it.

Hair Conditioner + Lye: Lye is a highly caustic chemical and can cause severe chemical burns...putting it in hair conditioner serves no purpose other than to possibly create a scenario where someone thinks it's a good idea to put it on their skin/scalp. Not a good idea. Don't do it.

Toothpaste + Bleach. If you can't see why this is a bad idea, you should give it a shot. I'll have your Darwin award waiting for you. Don't do it.

[–] Postmortal_Pop@lemmy.world 3 points 3 weeks ago

See, these were my conclusions for the first two. Mixing the two would imply using it on your hair and that's fucking dumb, but why doesn't it say "hair ruiner" or "scalp burns" instead of a the nebulous "don't".

Also, I use bleach and toothpaste as a cleaning agent all the time, putting it my mouth would be fucking dumb, but it's great for tiles and grout.

My guess? Huge explosion

Take toothpaste, remove the baking soda, get cooking oil. Got it.

[–] supergrizzlybear@pawb.social 9 points 3 weeks ago (1 children)

wtf is oobleck and bubble dough?

[–] clay_pidgin@sh.itjust.works 12 points 3 weeks ago (2 children)

Oobleck is corn starch and water. It's a goop when you touch it slowly, but solid if you whack or poke it.

[–] grue@lemmy.world 23 points 3 weeks ago

A non-Newtonian fluid.

[–] aeternum@lemmy.blahaj.zone 3 points 3 weeks ago* (last edited 3 weeks ago)

Otherwise known as non-Newtonian liquid

Years ago I was watching a documentary about trash and recycling. They interviewed the garbage truck driver who said people have to be careful what they throw out. The containers can be ruptured in the back of the truck and can mix. He mentioned brake fluid and powdered pool chlorine and coca-cola and powdered pool chlorine can be dangerous. One combination makes a poison gas, the other spontaneously combusts.

[–] j4k3@piefed.world 4 points 3 weeks ago

I think linseed oil on rags is one of the big ones that will spontaneously combust.

When I was painting cars, too much catalyst in composites can be one that gets hot enough to burn skin easily. I never had it combust but it felt close to hot enough a few times. One of my cheap and fast hacks is to use fleece fabric with fiberglass composite type resin. It soaks up a ton of resin and will take a shape in one go as something of a base molding form that can be worked with course shaping tools. That thick of material full of one mix of resin gets super smoking hot when the catalyst goes off.

[–] Battle_Masker@lemmy.blahaj.zone 1 points 3 weeks ago (1 children)

my dad used to do pool chlorine tablets in brake fluid as a party trick. it gave him a reputation among his coworkers's wives

[–] RodgeGrabTheCat@sh.itjust.works 1 points 3 weeks ago (1 children)

I'm assuming that's the mix the burns?

[–] Battle_Masker@lemmy.blahaj.zone 1 points 3 weeks ago

Idk if the stuff itself burns, but the gas it emits might. Also the reaction is pretty volcanic

[–] otter@lemmy.ca 5 points 3 weeks ago* (last edited 3 weeks ago) (1 children)

Hydrogen Peroxide + Rubbing Alcohol = ~~eye~~ drops? Why...

Oh nevermind, I can't read. It says ear drops

[–] slothrop@lemmy.ca 3 points 3 weeks ago

Heard but not seen.

[–] humanspiral@lemmy.ca 5 points 3 weeks ago

Anything interesting in the "Just don't do it" squares?

[–] Nomad 4 points 3 weeks ago (1 children)

There is a literal box showing how to make extremely toxic rocket fuel. (Hydrazine)

[–] j4k3@piefed.world 4 points 3 weeks ago

Acquiring high strength hydrogen peroxide is not easy or anything like the junk sold in a pharmacy. Same for ammonia.

[–] bluesheep@sh.itjust.works 4 points 3 weeks ago

Saving this for the next time I need some DNA extraction buffer.
