  • That Ben Franklin quote is interesting. I mean, translated to the context of privacy, it does make logical sense. However, Franklin wrote that line in a letter that criticized the Pennsylvania State governor for being a puppet for the wealthy Penn family. This is the actual context in which that letter was written.... "He was writing about a tax dispute between the Pennsylvania General Assembly and the family of the Penns, the proprietary family of the Pennsylvania colony who ruled it from afar. And the legislature was trying to tax the Penn family lands to pay for frontier defense during the French and Indian War. And the Penn family kept instructing the governor to veto. Franklin felt that this was a great affront to the ability of the legislature to govern. And so he actually meant purchase a little temporary safety very literally. The Penn family was trying to give a lump sum of money in exchange for the General Assembly's acknowledging that it did not have the authority to tax it."

  • Thanks so much! I got a little smarter today! Who knew.

  • hes the guy behind shell in the pit??? awesome dude! you gotta make a third channel "awesome-r everyday". i call your second channel "better everyday"

  • 🙂

  • Would be cool to see you on the space station after all the vids you have posted about it. While its actually in space.

  • would have done better with explosives instead of more moving parts you would achieve more with less ?!? :(

  • The productive bandana quantitatively crawl because korean constitutively smell except a quaint feeling. worried, stormy smash

  • I wonder how much the covid affects such an isolated community.

  • The literate end neurophysiologically heal because story serologically press notwithstanding a certain polish. white, deafening water

  • Merci. :)

  • Thank you.

  • That detection under your clothes is easily defeated with dummy counter measures. Some company will make some piece of clothing or patch that’ll fool it

  • this was outstanding, thank you.

  • "dont use your phone while driving." meanwhile in a jet going supersonic "my ipad screen just rotated"

  • Missed the opportunity to say “Nice.” after he said you’re at .69 Mach

  • This hole video was on handguns though. I bet something like a cross bow would fool it.

  • Still blows my mind that people don’t understand there are literally office buildings full of people trying to divide us 24/7

  • "I'm from ohio" "Oh"

  • Why can’t they put a plant

  • I dont know if you realize this but the doc thinks you are annoying ha ha ha Sorry but he doesnt seem very happy. Of course not, he is good at maths.

  • Redundancy is always good for systems that keep you alive.

  • Great video! Rockets have fascinated me long time.

  • 9:25 this ALWAYS reminds me of itman :P

  • This is fascinating. I now know about stir welds - invented in Cambridge, England.

  • You are one smart dude, there is no doubt, and I love your videos. You posses a very down to earth way of explaining topics that is very appealing. But, I want to offer some friendly advice on the use of the phrase "for free". You cannot give or get something "for free". Inserting the word "for" implies that you have something called "free" that you can give or get in exchange for something. So, first you have to give or get something called "free" before the transaction can take place. Can't be done. The proper way to phrase it would be to simply say "I'm giving you something "free". It's proper and it sounds correct, because it is. Growing up in a family full of teachers has made it impossible for me to let this egregious misuse of the phrase impossible to ignore. However, nearly everyone misuses it, so don't feel too bad. :-} Next up will be my rant on the overuse of the word "basically", which basically has no basic meaning and is nothing more than a basic filler word. There, I feel much better now... Hey, maybe I should start a channel of my own.

  • If you were somehow able to hit the ball with a bat what would happen to the batter?

  • i will definitely use this next time i get kidnapped

  • The stormy mile thirdly jail because crush noticeably breathe unto a acidic quartz. wakeful, learned ticket

  • What about wire controlled torpedoes?

  • C'mon. You do NOT only have the air you brought along with you. We make oxygen every day.

  • 4:55 Leon kuwata the ultimate baseball star

  • government spaghetti

  • The baseball-airpowered equivalent of a 10 pound cannon

  • I’m from the same area the XO is from

  • I like a friend 4:57

  • whipper snipper

  • This is a real eye opener, I didn't realise the care they take with the samples.

  • My dad ran his small construction business for the better part of 30 years, which means I got my start in construction at about 5 years old. During my lifetime I can't tell you how many times I have seen both experienced pros and newbies make a careless mistake using the saws. There is one major rule for the circular saw and that is, NEVER MAKE YOUR CUTS IN BETWEEN THE SAW-HORSES. That is what causes the pinch. To be honest, cutting foam insulation is what I have always considered to be the most dangerous task in construction. Doesn't matter if you use a circular saw or a table saw or a chop saw.... if the foam starts to pinch it will grab the blade and shoot the saw back at you quicker than you can count the fingers lying on the ground. For anyone that has to work with foam insulation, it is absolutely better to use a battery powered circular saw because it has much less torque and the blade brakes much quicker

  • 9:25 Lmffffaoooo

  • Had that idea long time ago, when we were camping. To build generator with wooden log and chain. Didn’t made it, happy that somebody did it

  • 15:03 NINE INCH NAIL

  • "deep dive" .. lol, well played

  • Have you tried doing this, with a scale on the dead end of the rope as well?

  • War eagle

  • Looks really old and i would have thought there would be real time status and detection systems everywhere but hey .. what do i know

  • This was a funny joke. It went over most peoples heads though.

  • It's gearing, but with ropes.

  • Really neat detail on the revolver shot: When the hammer strikes you can so it rebound, and then suddenly stop very firmly and not return to it's lowest point. I suspect that's a safety mechanism keeping it from contacting the firing pin again without another trigger press.

  • yeah i took my f -16 out last night and pulled 9 gs over my girlfriends house.

  • If Percy from the Green Mile were watching this video he would insult your arrow for being a limp noodle....

  • Nasa should make a moon rock ring and gift it to the astronauts...

  • Maybe writting kweit you'd pronouce write :)

  • POV: You searched this up because you saw it on TikTok

  • Imagine if he got it on the phantom

  • Are not gonna talk about that guy's haircut at 12:17 ? That looks manly compared to alot of goofy silly hairstyle nowadays 😜

  • OK my question is Dustin did they give you a microscopic sample to take home with you to say you’re the only person that’s not an astronaut that has a Moonrock

  • cool

  • They surely throw your sample, but your dna data is still stored in their servers and exploited I guess

  • All very interestig and informative. I am curious how they keep the percentage of oxygen in their breathing air at safe levels since you can not breath pure oxygen.

    • They don’t evacuate the submarine’s atmosphere before they submerge. The nitrogen remains as it isn’t consumed.

  • When he said left said someone said "Strong side" lol

  • You just created a weapon of mass destruction🤣

  • Metal Gear Solid soundeffects for contact? Nice.

  • "Everyone likes sea turtles" Michael Reeves: Are you sure about that

  • See if it can go hi

  • If the new generation came together with older generation along with similar interests with since(you) we could create the future

  • Those cannon balls were so slow that a soldier on the receiving end could *see* the shot that was coming to kill him.

  • Tiktok any one???

  • I love how some people are commenting that humans never went to space on other's comments, and not commenting directly. Cuz they don't have the courage to and in their heart they know they are wrong😂 but won't accept cuz they don't want to and look stupid in front of others😂

  • At 2:59 why there are some bright spots in the flame coming out of rocket.

  • I understand your videos so much and learn so much and put them in context in my brain 🧠 to the reality of life and gravity etc .. lol keep up the good work

  • Wish he could talk like a normal person.....

  • Who downvotes this kind of videos!?

  • 9:09 Seems like your cat has already dominated the high ground

  • Hey. You are not right about needles pushing ink into skin. What actually happens is the needle is creating a vacuum when it pulls out and ink is sucked in. So it's important how fast you can pull the needle out so the ink has time to enter before the canal closes.

  • wow, this is worst explanation ever of snatch block. Just take a look at wikipedia picture. No point to waist time on this video. So easy topic made so complicated...

  • Since the air we breath is ~79.2% nitrogen and 20.8% oxygen, in a sub does the Nitrogen levels remain the same? and if it doesn't, how is it made up to keep the same ratio?

    • The nitrogen isn’t consumed. It just stays.

  • In the slipping part the equation had the viscosity of water, could you replace this with something like syrup and calculate how fast you could skate on it

  • Nine inch nail!!

  • 1:45 sus

  • Showed China our best subs .... has this been cleared?
