Do Not try to charge a LiPo Battery like this! 

FIRST Hit the video with a thumbs up if you liked it, don't forget about notifications too! Whats inside a battery? Regret...and Fire.

What was it Adam Savage said? "The Only Difference Between Screwing Around and Science Is Writing It Down"

I love that you added the “don’t breathe this” from the blendtec guy

About 40 years ago I worked in a Navy R&D facility that started using some of the very earliest prototype lithium batteries which were made by GTE. I don't remember the exact chemistry but it was a double D size that was 3.6V/10Ahr. Massive capacity for the day. Turned out that GTE never tested the proto batteries for what happens if they got shorted. Since we were going to be putting the batteries in things that would be in salt water, we did. They EXPLODED with a force equivalent to 1/3 stick of dynamite. GTE later solved that minor testing oversight. I believe they put a compound into the mix which impedes the rate of discharge so they won't explode. I believe that's true for most (all?) lithium batteries. Now they can just overheat and catch fire.

Laser canon AND defusing bombs? **laughs in FBI**

Every episode you post just further proves that my Elementary School teachers were wrong when they told me that "Mad Scientist" was not a viable career path.

4:06 famous last words

4:49 at this moment I can see a real version of Dr Doofenshmirtz

Haha this was great. We've poked holes and over-charged a 6s 6200mAH -- nice fireball from that!

I love it how you explain how dangerous the laser is, then point it towards a road

him: 'smokey smoke, dont breth this" the neighbour: "hmm they are making a bbq" also the neighbour: *dies of toxic gases*

2:07 POWER!! UNLIMITED POWER!

I love how he casually owns all this stuff that could start a revolution, laser cannons, flamethrowers, you name it

Dadgummit man! I approve these shenanigans

Just want to say you’re experiments are an inspiration,I’m a local of Florida with no education yet thrive to understand science and what it has to offer . Would love see an experiment first. Keep doing what your doing and get the world excited about science #backyard Scientists for life

I've opened a few lithium batteries recently, after one managed to be punctured inside the laptop and literally melted half of it nearly setting the house on fire I've found them fascinating. I have high school level knowledge of biology and chemistry but I never understood why a punctured lion battery had a very aromatic, sweet smell when disturbed, until you mentioned the organic solvent contained within.

Well, now I know to make sure not to incinerate my LiPo battery with a 30w fiber laser in a pure oxygen environment.

My chemistry teacher showed the video of you putting molten salt in water to my class and everyone loved it.

"Don't let it overcharge" "What you mean 'overcha-'" *loud explosion sounds*

Goofing around and having fun in the best ways!!! Thanks again for this

@ TheBackyardScientist I’d recommend mounting a normal green laser on the big laser o death thing to help aim it.

67 degrees chilly XD Laughs in northern

You are my kind of scientist and perform great experiments!

I remember attempting to replace the lithium battery in my old phone. I had to use a knife to separate the battery from the case because Apple uses an absurd amount of glue to hold them in place. Anyway, I poked a hole in the battery, magic smoke went everywhere, and I was sick for the rest of the day because apparently your not supposed to breath that smoke in

Instructions:DO NOT- RU-vidr:Hey guys today we are blowing stuff up

See, we need people like you in our lives! Keep it up

3:36 I hope it is natural fibers as well...

*OH MY GOD!* *67 degrees oh you poor thing that’s just absolutely freezing!* *-Love from -40 Wyoming*

This is one of those videos where I will actually heed the "don't try at home" warning

1. Liked it! 2. No advertising, loved it!

That laser telescope thingy is terrifying. That's a lot of energy

More telescope laser please, like test how far away you can light stuff on fire from, love your videos

Good luck finding a reasonable quote on life insurance. On the bright side who ever writes your obituary could have a best seller.

You sir, are an absolute madman.

Battery: says not to do stuff Backyard scientist: looks like it’s Opposite Day!

"it's down to 67 degrees so i grabbed a jacket" kowalski, analysis

*the next flex tape commercial is here* I sawed this battery in half!

The battery blowing up was awesome. Probably my favorite thing Ive seen on this channel!

One of those blew up in my hand, I was very lucky that I had gloves on and that I was able to throw it outside before it caught anything on fire

3:14 You can overcharge an LiPo Battery, but the question is...will it blend?

Ahh, this was beautiful to see! Nice vid man.

lol you're like Rick from Rick and morty. mad scientist vibes lmao love it. Keep on keepin on brother

Holy crap, was that an audio clip from Will It Blend at 3:15, love it!

Styropyro would be proud!

“It’s getting a little chilly it’s down to 67 degrees” lmao

Love the blendtech Will it blend reference. My childhood right there

TBS: *makes a 30w laser cannon* StyroPyro: are you challenging me?

The perfect battery has both high power density and current density. This requires an intimate mixture of fuel and oxidizer; also known as a bomb.

“It’s getting a little chilly, its down to 67 degrees.” Everybody who lives in or near the Rocky Mountains. “Really?”

Nice to see that some instructions don't lie

Uses high power laser, points it at his gate so anyone walking/driving behind that will be in its line of fire, then uses a invisible spectrum so you get no warming when your eyes melt.

For maximim effect, charge slowly to about 4.7V so the lithium actually contains all the energy possible

Enjoying what you do here. make sure to up your safety game so we can enjoy for a long time to come.

6:31 that was like a firework show

"It's like trying to defuse a bomb... wait can I say that?" "No" DEMONITIZED! 😆😆😆😆

glad you are the one doing the goofing Good on your crew

OMG A LEAK OF THE NEW NEXT GEN WIRELES CHARGING.... OMG 2:27

You are an irresponsible fool. Love your videos.

I'm glad i saw this, i was just a few minutes from trying to charge mine with the 30w laser. glad to see you're still making videos and (hopefully) not getting hurt in the process

Thank you man you teach me a lot about this stuff I love your videos to

Florida man: puts on jacket in 67 degree weather Me: laughs in midwestern

Wow. That is actually *EXACTLY* what i thought would happen if you overcharged a battery like that.

1:34 now i see how magicians do the fire trick

battery: "combusts" ... ... sandra: "...oops"

“Getting a little bit chilly, it’s 67 degrees”

4:25 Rip GoPro

Laser and exploding batteries... Not something crazy. Got it. Hahah

Thank God you were wearing your OSHA approved hoodie and sunglasses! 😅 I wonder why firefighters aren't using them. Great video, please keep making them!!

Sounds like a regular Sunday afternoon really, awesome 😎

GOD : do not eat that fruit RU-vidr : HI WHAT'S UP GUYS, NOW WE'RE GOING TO TRY TO EAT THAT FRUIT BECAUSE GOD SPECIFICALLY SAID DO NOT EAT IT GOD: am i a joke to you?

6:12 you should sell that weapon to the military

Will It Blend is the bomb, great reference!

“Little bit chilly it’s 67° right now” Bro it is currently 22° right now for me. You are a true Floridian

"Its getting chill, its 60 to 70 degrees." *Disapproves in Oregonian*

This is awesome! I work in a battery franchise store but I’ve never seen a battery blow up on anything other than security camera footage because it’s rare that someone tries to video it as such a close range in such an awesome enclosed environment. Amazing!

I don't know which is better, the projects, filming or the jokes.

"I thought it would be fun to try all the things it says not to do . . . " I love it. Very funny.

I could smell the fumes through the computer

“This will be fun” Newly discovered survival tool to start a fire, Lithium Ion Batteries

You are cold here in Maine the temperature you said we call summer love your channel

love the will it blend reference

Imagine who had to figure out all the things that you shouldn't do to these batteries...

You cannot charge a lithium battery via a tesla coil because of the floating voltage. The voltage of tesla coil is high but the circuit just isn't complete. There would be no current flow and no overcharge. To actually overcharge a battery charge it fully, then connect it to an unregulated DC power supply. The battery would heat up and swell. That's when you know that you have done it right.

i love this kind of content!

That just reminded me of all those old RC plane packs that I need to get rid of 👍

2:40 when apple says that they have super fast wireless charging

"Hey, my phone's almost dead. You got a charger I can use?" This Dude: "Uhhhh... Yeah... As long as you like Fires"

Goofing around and having fun instead of something crazy? Well now I am scared what "crazy" means. Good job. 👍

thebackyard scientist im a big fan of you kevin please make more fun science videos

4:17 One like=one respect for this gopro

I love the small editing, they're very simple and charming. And as a video editor, I keep thinking how I would love to edit these videos.

I didn’t here or see any ‘don’t try this at home’ warnings, so Imma go do this now

That battery manufacturer had some good lawyers writing those warnings.

4:33 That poor GoPro...

0:01 *clears throat* Lithium Polymer

"Goofing around and having fun" Ah yes, remember that's time where u decided it would be a good idea to point a destructive laser at a small battery

The GoPro taking the flame to the face at 4:27 was worth the watch, in and of itself!

"it's a little bit chilly" "it's down to 67 degrees now" make up your mind, either its chilly or it's warm

Lol I'm sitting in MN when it's -37 degrees out
