Quick clarification: For the candle trick, the reason the water actually flows inside is because the oxygen on the inside of the bottle is used up, thus reducing the air Pressure! To check out the next episode of testing TikTok Life Hacks: ukposts.info/have/v-deo/oXSVgmuahnxzkps.html

The fact that arun tapes led light bar on his kitchen floor just to create an atmosphere shows how much work he put in.

Arun is always one step ahead compared to other youtubers. He not only tries all these tiktok hacks, but teaches us what the thing actually is or how it works. Top notch mate

“Just say next and it wor-“ “You out da blue need to use da bathroom” got me crying of laughter

I love how Arun was concered for his hair and excited for the last experiment. Right after it worked his tears of joy turned into real tears!🤣

For the hair dye to work you need to either use bleaching before blue dye, or use a dye that includes a lot of bleaching (which usually works less well).

The bread and butter one was SO SATISFYING and I loved it. It made my mouth water too. I love u for doing that Arun!

4:02 THE BATHROOM 💀

0:45 That toothpaste is magical. It not only repairs the broken screen but even makes the phone rectangular all of a sudden.

11:30 when u realize alcohol is flammable 💀

This is amazing The candle and screen shot one is really cool😊

The guy with the I need the bathroom song on tiktok is the best 😂😂

12:21 He literally puts in the Konami code on the claw machine lol

That guy in orange at 13:01 looks like he wants to steal the moon

3:48 I just thought of a way to use this to listen to music, and change the song without touching your phone, like when your in the shower Basically make it to where when you say like next song or next video etc, it presses the next video button

The screenshot one when you change your rubbish circle to a perfect one, works with other shapes too (squares, triangles etc), but gets confused a bit when you go beyond a five-sided shape. Not sure how useful it actually is in day-to-day life but neat nonetheless!

8:08 That is very, VERY dangerous. The only thing keeping the heating elements from melting and catching fire is the flow of cool air. If your hair dryer is old and doesn't have a safety system, it can burn down your house.

This is the best video I ever seen thank you so much

We need more of Josh he's so funny😂😂😂😂

12:48 Vector lmao! OH YEAH! You just got vectored!!!

9:07 Correcting a few stuff here. First of all having the inside hotter would only make the pressure inside higher. Secondly, that happens because fire needs oxygen to continuously burn as the oxygen use up the pressure decreases, pulling in the water around it to about 20% of he volume since that's how much oxygen in the bottle and atmosphere.

Congrats on 16 million!

9:40 Reminds me, when I worked at Starbucks we would heat milk jugs up with the steaming wand on the espresso machine to make squishing the jugs much easier. Legitimately quite useful. Also that RAM one was brilliant 🤣

10:30 lol

About the battery light bulb one: In the first clip, they connected positive terminals of the batteries to both positive and negative terminal of the light bulb, which means, there's no way for electricity to flow. In the 2nd clip, they've connected the terminals right(except for the 2 positive terminals touching together, that doesn't do anything in this case), but there's still no closed circuit, They'd have to connect the free terminals together to close the circuit (and turn the bottom battery around, so the positive terminal touches the negative terminal). So basically just running the batteries in serial connection to increase voltage to a higher amount. I've made a light bulb run on 60V from serially connected 9V batteries.

I like how you logically explain the flaws in some of these. We did the candle experiment in school but it doesn't explode like that tik tok claims

YOU ARE ACTUALLY THE BEST TECH CHANNEL! Keep up the engaging and entertaining content! How did you make the part at 2:26 where the fried egg flies off screen like a "Star Wars Plane"?

13:36 Did he just say “Nein!”

Definetley want to see more of the team in your videos... If Arun on his own is great then the team would surely be entertaining

“Why do you need to the bathroom”😂😂😂

I think they test beforehand to make sure it's almost exactly half but one over so he gets the hair and the viewer gets the reward for staying tuned

For the light bulb trick at 7:10, even if the voltage was right it wouldn't turn on because the circuit is not closed. It's basically an open breaker

thank you for testing all tiktok lifehacks it must've took you a lot of time ❤

8:15 - the hairdryer isn't broken, it's just a fail safe that shuts down the dryer if its airflow is poor or it gets too hot. The spark is normal when safety engages, leave it for a few minutes and it will work again.

I am an Irishman seeing potatoes being wasted almost gave me a stroke

for the ruler trick, using a wooden one, and using your hand to punch it as hard as possible, it can snap in some instances. its because its spread force alone the paper.

This is what sets Arun apart from the rest of the crowd. He doesn't just do a thing and shows it working or not working. He explains why it works or if something doesn't work, explains why it doesn't or how it has potential to work if done a bit different. Top notch content.

Hair dye doesnt really dye dark hair that well so you need to blonde/bleach the hair first but anyway, great video!

When cat comes up to the table Arun smile🤭😂

The candle trick is just the candles fire taking air minimizing air pressure, which causes the atmosphere to higher the pressure and therefore creating a suction force trying to pull in air, but there’s only water so water goes in

9:57 "that's what she said" guess no one else noticed, that's why the reply rte is so low there

You never seem to disappoint. Thank you for lightening my day

Amazing job mate

he literally looking like he's about to say "ahh perry the platypus!

13:05 bro man looks like the nerd from minons LOL

8:54 I got life insurance ad here 🤣🤣🤣

i just saw an opera GX browser ad with you in it while watching this video with you in it lol

in the 5:20 moment you showed like that apple fixes you circle in a screenshot drawing, and i checked it and it actually woeks with any other shape! worth a try!

13:21 Mickey!! 🤣

9:23 I knew about this one. I worked at Starbucks for about 6 years. We used to steam the milk jugs with our steam wand so that we could crunch them up quickly and make more room in our recycling bin. It’s astonishing how small they can get 😂

I need this man as my physics teacher 😅😅

Bro just became a scientist 6:19😂

6:28 this one explanation now makes me really want to see Arun do a crash course series

I like how this series is just a way to have Arun try different things to do with his hair and monetize it 😂

first he says the heat will make the volume smaller (which is wrong, it is because of the oxygen burnig) then he says the air expands and make the cork fly up XD, I love his vids

11:22 his home is like a palace

The marker trick is kinda true. Yellow and green highlighters are very visible under blue filtered light (much more so than in regular light) which stage technicians use to for example make notes behind the stage where we can only have a little bit of blue light. Yellow light would often be visible to the audience. It's a bit different between different highlighters though how well you can see them, and I have never tried diluting one...

Thanks for the really good content super funny

You're supposed to strip the color out of your hair before you use that kind of hair dye. I used to use it all the time when I was younger. There is/was a product called seventh stage I used to use to strip all of the pigment out of my hair before putting the blue gel dye in. Since the bright colors like this usually only come in a one-part semi-permanent dye they generally do not have the same developer and other ingredients that let it really chemically replace your current hair color. So you have got to get rid of the current color first and start with it as light as you possibly can. On top of bleaching or stripping your hair first, It's also best if your hair is as dried out as possible when you put the gel dye in (the blue stuff) And then you always want to let it sit for a little bit longer than the bottle says, and then without rinsing you add conditioner first and a lot of conditioner run that through and then rinse lightly WITHOUT ANY SHAMPOO AT ALL and dry it thoroughly with a towel that you don't care about because it will shed some dye for the first few times you wash your hair. That's just how those semi-permanent dyes are. It will also shed a little bit anytime you use hairspray or any alcohol based hair product or anything particularly acidic or corrosive or that "opens up" your hair (kinda like how heat opens up your pours) a lot... Enjoy. Love you guys. Kay byeeeeeeiiiiiiii

11:10 everyone has done that at least once

4:00 tho

4:01 I got an add the moment you said next🤣

13:27 i love it when british people say this

10:30 I love how he just walks in, sees Arun doing a Tiktok lifehack, and just dips

he is good at hooking people in. his vids dont get boring and stay entertaining the whole time

8:18 the hairdryer was sparking because it needs the airflow to cool down the heating element and prevent it from melting, restricting that airflow resulted in that heating element melting and since the heating element is also resistor limiting current to the motor in the hair dryer it stopped working completly.

You ARE A GENIUS !!! EXPERT IN ALL FIELDS

Great content I always love watching your videos!

Amazing to see how far you've come....I think I speak for a lot of us when I say you're the greatest tech UKpostsr.

I love your Videos!

The video... I NEED TO POO IN THE BATHROOM 💀

You know what I love about this video It's the fact that they take the time to actually go in to depth with some things like further explain instead of just checking the hack and getting it over with

7:11 This reason for why it doesn't work is not wrong, but it's definitely not the main one. The circuit is just not completed, so there is no electricity flowing. To complete it you'd need to connect the negative poles of the batteries to the light bulb as well.

This guy is science technology teacher (compliment)

I love how in the left corner the whole time there's a picture of him with blue hair. You don't even need to watch to find out

For a smart guy, your shock that water glowed when a light is aimed at it was hilarious 😂😂 Great Video btw 🙌🏼

Intrigued by this one!! 😬👌

5:19 is that the sound effect for being awarded points in pokemon contests? 😂😂

I love these videos

Physics and Chemistry debunking/teaching with Arun :) Loved it mate

Arun never fails to entertain us. He did a lot of risky stuff in this one

11:11 *"...all the lights on and than- WHOA!"*

I tried the hack. Where are you circle some thing on your iPhone after taking a screenshot. It turns out that any shape you make almost it will mimic and correct the shape. I just tried it with a star a square a sort of cloud shape, a circle and a triangle. My grandson and I are excited for you to try it!

For the candle TikTok, we did a similar experiment in science class. It was boiling water in a 12oz can(small amount) making the can fill with steam replacing the cool oxygen. Then we dunked the van into cold water(opening first) which makes the water vapor holding up the can condense therefore making the can collapse on itself and crush. It was really cool but I had to wait like 15 min for the water to start steaming on a hot plate

Thankyou Arun for teaching us . Everything in technology . ❤️❤️❤️❤️❤️❤️ I leaned a lot of thing from this video ✨✨✨

The fact Arun just puts a metal butter knife in a plugged toaster oven 💀😭

The scene with the ruler and the paper....you had no shoes on 😭

Someone had to say it... The reason at 7:09 isn't completely correct... as the 1.5V potential difference has nothing to do with the trick not working... It's simply because the circuit is actually open.. so no actual current flows through the lamp. :)

For the squiggle hack, it also corrects triangles and squares if you draw them and hold as well. Also a straight line if u were underlining something.

 IM OBSESSED IT WORKS

" Hahaa! It's A s CD Bubble!!.... oh dear god..." That was the funniest Thing i've seen all Day!! - Thank You Arun!

You are such an amazing UKpostsr bro, please never stop

The only UKposts Tech Channel which never disappoints... Love your content ✨✨

6:23 well it has noting to do with the atmospheric pressure as it doesn't depends on the surface area. The real concept behind it is the viscose force or the air drag with depends on the area. 7:13 it doesn't work because the circuit is not closed in the first place. Even if we use 220V ac and connects its one terminal, it still wont work

the one with the lightbulb probably also has to do with the fact that they put + on + and that obviously doesn't work

Your my favorite youtuber!!!! You taught me so much about tech!!! I'll be looking out for your next video. You get a five-star rating!!! I've seen every one of your videos!!!

The spark inside the hair dryer was the thermal switch stopping the whole case from melting because of restricted airflow. It should come back on in a few minutes

2:28 imagine your fried egg flies into your roof😂

Du bist der beste UKposts für einschlafen

Just love the reaction change from 13:26 to 13:28🤣 Thank you, Arun, for such enjoyable content!
