How to Kill a Planet: explosions!

[pfunkmalfunkshun]

lucky!! i got a universal machine pistol with a silencer to get past the long barrel you need to get a civilian model and i had to order a military lower to get it to take real high capacity mags the civilian model when you first get it is a pussy pistol but it can be rebuilt with a parts kit at home 10 rounds only single stack fuck that now i got 45 rounds semi auto for now  i don't need full im a collector not a merc;)

[janemidnight]

Was that gun range Ben Avery's?

[mvszao]

SO COOL! You see the explosion and THEN you hear the shound and the camera feels the shockwave. It's awesome!

[rerere284]

LIEZ!!!

:P

[anthonzi]

Low caliber is low

[spacedooky42]

When he was firing semiauto the recoil made it seem like a GSG5, not a MP5...he has good gun handling.

[expalman]

The guy off camara was much better!

[pookabun]

Boys and their toys. You just wanted to use some neat explosive materials and blow stuff up.

Admit it! :-)

[AnimaRaptor]

Well.... yes.

[ireme149]

i also thanks,now i know how to blow up my

neighbours to mars with ammoniumnitrat+6% nitromethan-haHAHAHAA-ONLY FUN.

*****

[randomjunkguy]

or you can set fire to there gas in the basment

[sceptiquepower]

Great!

[RationalFuture]

Thanks for telling me how to blow up my neighbours :)

[gavinmacmounsey]

How to kill a Planet eh...

Personally, I`d be more worried about GRBs taking places in our nearby "cosmic neighborhood", and the chance of one being directed at our beautifully diverse, yet fragile Planet.

but I get it, Antimatter vs Gamma ray bursts, the explosives get the air time....= )

I don't like guns Phil. Not a good look. Even if you are an astronomer. I would hate to see an astronaut use a gun!!!

[BjornTuRok]

Then he's not an astronaut. He's a SPACE MARINE! PEW-PEW, KABOOM!

[spacedooky42]

Apparently the Russians kept an AK74 in a storage cabinet in case they crashlanded in the middle of Siberia and met a bear.

[CanadienAtheist]

Very cool stuff.

[Hairysteed]

I wish Astronomy was a voluntary subject in our upper secondary schools!

[frededison]

Mankind has created a total of 20 nanograms (nano = one billionth) of anti-matter, according to the program. The BA "blew up good" used one pound of TNT, and was a comparative demonstration of that amount of anti-matter reacting with matter. Don't try this at home.

Cool show and nice job, Phil. Good form handling the weapons, too. Thanks for making the video.

[JustAnAdjunct]

Scientist with a SMG = AWESOME!

[TheBadAstronomer]

BrilliantAdventure, it aired last week. But I'm sure NatGeo will replay it quite a bit.

[BrilliantAdventure]

cool, when is this episode going to air?

[mhrumman]

the background gun fire probably used to mask whats he is saying

[Chick6517]

OoO that was interesting hahaha.. but yeah i enjoyed this video.. fun, entertaining, what more could i ask for. hehe :]

[saintaureus]

Bah, these explosions are tiny. On the last episode of Mythbusters they detonated 5000 pounds of high explosives to make diamonds. I guess I'm a little jaded.

[MattUK2007]

Hey, this guy got contacts....remind me not to piss him off.

[lennyhipp]

saw the show the other night... it was great... until i realized you weren't going to blow up the planet after all, just talk about HOW you COULD blow it up! How disappointing! :))

[midas41]

I didn't think you were allowed to show bomb making on Youtube? Maybe you should check - don't get a strike.

[anothersquid]

Making explosives is not difficult and does not require much intellect nor complex instructions. There are 2 difficult parts to making IEDs, however.

1) making the bomb safe enough to transport. That requires a goodly bit of brain power, training and instructions.

2) Related to the former... setting it off so it works, and goes off when required. That is also a lot more work than it may seem.

But mixing chemicals? That's just dangerous - a "don't try this at home, stupid" sort of thing.

[Krumbz2003]

Not bad Phil... not bad at all bruddah!

[neverlookback75]

sweetness, can't wait to see it on tv.

[batlrar]

I would like to suggest putting annotations or captions on the part with the gunfire in the background, as I'm sure a lot of your fans are interested in what you had to say in that part.

Also, wonderful explosion!

[BitchesAndHose]

1:19 and some out, the guy looks like he has only four fingers xD

[Milenium412]

AHAHAH GUNZ

[Brianswers]

Cool, looks like fun. lol. How do explosives simulate antimatter?

[dabocx56]

I think they were talking about how little anti matter it would take to simulate that explosion

Something like less than a gram of antimatter is more powerful that so much tnt exc

something along the lines of that i think

[shubidubar]

nice

[GoblinXXX]

LOL, "Hollywood sits on a throne of LIES!" You got that right, buddy.

[NAMLegolas]

Nice, Lucky you!

[PsychoBlack]

I saw the show last night Phil. I missed the part about "Nanomachines" though.

Overall, I loved it.

[Nuckpang]

So you're a fire eating, gun toting astronomer with a thing for big explosions? I will be on my very best behaviour at the amazing meeting...

[CousinoMacul]

So Phil,

You've moved from big telescopes to big guns?

;-)

[MiGP1981]

5 stars!

[noswonky]

Was that the Big Bang?

[Clausfarre]

Phil, we've missed your work since you became our president (change you can believe in!). You're the best so I'm thrilled whenever you upload videos.

[winstonsmith00]

Looks like fun.

[thirdclass2006]

The Phil-O-Nator!

[demonslayer55555585]

seems like you can never throw that thing far enough.

The BOOOOM!!!! always gets ya!!

[longhairred]

Science rocks! And blowed up real good! ;P

[NoSz4]

awsome phil!!

[philkarn]

nitromethane plus ammonium nitrate is just what McVey and Nichols mixed up to blow up the Oklahoma City federal building. He wanted to use hydrazine but couldn't get enough; nitromethane was available through racing suppliers.

5 pounds TNT is about 10 MJ or roughly 100 nanograms of matter being turned into energy, if my calculations are correct.

[login2587]

great shot but its a bit typecasting to show u shooting a gun.

explosions looked a bit small.

putting the charges underground would have helped showing the force of the explosions.

flying dirt is a better visual then airdisplacement ;-)

to jamesTCA: if u like the mp5 u will love the p90.

[NateBlack0]

Lies upon lies! We all know that you recieved special training to defend super-secret NASA complexes when the aliens show up.

But seriously, nice shooting.

[Clausfarre]

Yes, everyone knows that he is a shapeshifter and that he rigged the moon landing and killed JFK - but we still love him.

[JamesTCA]

Good burst fire. I wish I could have an MP5 out here in Kalifornia.

[MaxSafeheaD]

Looks like the ultimate stag event, all that's missing it the titty bar =P

[windyshrimp]

You just need Adam Savage laughing in the backround.

[Harekiet]

It's not exactly mythbuster sized explosions, but we always like it when things go boom!

[mconn2112]

Gets to watch stuff get blown up and shoot a bad a** gun. Nice. :-)

[EldricIV]

You were in Phoenix and you didn't tell me?

[ccaptorchen]

nice mp5

[666norton420]

WOOT!!

you da man phil!

;d

[Woad25]

Hey cool thanks for the recipe to make our own explosives ;)

[rakatikie]

lol you never heard of the internet before? =P

[Woad25]

The internet?! A jest surely thou speaketh! :)

[everynameistakenomg]

Phil Plait: astronomer, writer and marksman.

[polysmart]

Phil with a semi-automatic! Run to the hills! LOL :)

[11mc22]

Couldn't hear much because of the guns

[tobascodagama]

So we can add you to the list of gun-totin' skeptics, along with PZ and Ben Goldacre. ;)

(PZ's gun was bigger, though.)

[CalebMTurberville]

Is this a metaphorical gun you speak of, or did PZ actually pack heat?

[tobascodagama]

It was a Vegas thing. ;) He doesn't own one or anything, but it was a real, literal, bullet-shooty gun.

[muckerfooker]

nice 1

[xdrawnout1]

awesome
