This channel, along with every video that has or will ever be uploaded on this channel, will be deleted after our year has ended. This is inevitable. Inescapable. Irreversible.
Do not archive or re-upload anything. This is our last wish. Our parting gift. Stay true to the purpose of our final year or we shall lay down wrath upon those that attempt to escape the end.
Memento Mori.
Unus Annus.


  • Every time Ethan talks history: Mark’s “the F?!?!” face

  • 13:22 Markiplier pog,

  • Ethan is such a good soft boi and needs to be protected at all costs..... like 11:05 lol

  • 13:22 Mark's Orgasm Face

  • Stop the clock.

  • Mark: I have an idea, I may have to sacrifice myself for this, but I fell like it will be worth it Amy: You gonna put it in you mouth? Mark: Nooo It make me wonder what things has Amy seen Mark do in the past that made her feel the need to ask that question

  • The plane was made before the bottle rocket

  • Taking selfies be like: 3:36 to 3:42

  • For a split second I thought when it actually worked that it was an edit.

  • 14:06 that did not sounds like amy 🤔

  • 9:26 This has me giggling like a toddler

  • "We're disclaiming that we don't know what the fuck we're doing" The way Eef giggles when Mark gets it to work

  • Watching Ethan explain the history of bottle rockets gave me an aneurism.

  • This was on my birthday and I like space

  • The fact that Ethan paints his nails gives me so much life

  • Memento mori...

  • i really gotta wonder why they didnt just do pop and mentos

  • So what i do in my neighborhood is similar to this everyone should knows this but uh Empty a water bottle a put vinegar in the bottle, take a paper towel and pour a little bit of baking soda wrap it in and stick it in the bottle quickly close it shake it and throw it hard on the ground and BOOOOOM EXPLOSIONNN

  • Normally the banter is funny, but tbh Mark was too childish and petty in this

  • 13:23 Mark pog

  • Also, an idea for the Disclaimer Song (tm).... A parody of the “Wrong Number Song” from Undertale Oh, it’s the disclaimer, the disclaimer song! Don’t try this at home, it could go very, very wrong! Oh, it’s the disclaimer, the disclaimer song! We don’t know what we’re doing, and it could go extremely wrong! (Lyrics/rhyming to change because I came up with this on a whim)

  • Unnus and Annus: A classic science experiment! Me: BAKING SODA VOLCANO Unnus and Annus: bottle rocket Me: EVEN BETTER

  • 14:05 Definitely the manly voice of Evan. Editor: This was definitely Amy speaking, for sure Lmao you got so close

  • October 24th. I continue my journey to rewatch all Unus Annus videos before it's too late. I liked every video on my way here before but some videos aren't showing the likes. Make sure the thumbs up is blue friends. Wish me luck, brothers in death. Memento mori, Unus Annus.

  • I'd love to take a look at Ethans book of Rocket History xD

  • Ethan: bottle rockets were the first thing to go into the sky Me: *flashbacks to reading October Sky in 7th Grade*

  • am i crazy or was that the song from ryan higa's dancing without moving played at 3:35??

  • Nice video

  • And on that day, Bill and Jebadiah Kerman went to the MUNNNN!!!

  • I was here!

  • Wow

  • Right after they cheered the soda I got a sprite commercial

  • I know I'm late to this but can I just point out that I think Ethan is good at drinking games. There is now way Ethan could have drank that with out pressure in his chest unless he was used to it.

  • am i the only one who's going to miss the unus annus music? now i have no idea if it's just some royalty free stuff and i can find other people use it (probably) but I just connect it with this channel now. (especially the mysterious sounding one)

  • Ethan's Hand: *exists* Scissors: Is for me?

  • Mark’s shocked face at 13:21 is absolutely priceless

  • Poor Mark. He lost Dr. Dynamite... RIP Dr. Dynamite

  • Memento Mori

  • Someone is in the window 13:30

  • I'm going to miss this video

  • The way Mark and Ethan fought over Ethan taking off the Dr. Dynamite label is how my siblings and I fight... "Well I just find it funny that you didn't have a semblance of thought until our older sister said something!!!"

  • Lol i love Ethans stupidity

  • flash back to benja channel, the most savage family on youtube XD

  • 13:31 wow just wow

  • i want the stickersssssssssss

  • E

  • ethan kinda sounds like sokka sometimes

  • Ethan: First thing to ever go into the sky Nature: Birb?

  • I hate that this channel will be deleted after the year is over...

  • Mark was so excited when his bottle blasted off his hand!

  • RIP Dr. Dynamite

  • the first flying objects a plastic bottle rocket

  • 14:33 PLUS ULTRA

  • Ok someone please help me out what is the orchestra music called? I hear it in other videos and I wanna listen to it.

    • (Edit) time stamp to let you know which music: 9:46

  • Absolutely 0 people missed Mark making a cocaine line out of the baking soda. Tbh I'd have done the same tho

  • Watching from the future! I am liking and commenting every video!

  • 9:30 *“Can I get a nyaapkin?”*

  • Because Amy is the voice of reason and Mark yells at Ethan all the time! That's why he listened to Amy.

  • Bottle or water rockets begin to be used in schools about 1973. According to a NASA website.

  • I have just figured out that unnus annus is also helping me with my science homework

  • *♩ ♪ ♫ ♬ The space is cOOoooOOooOol...♩ ♪ ♫ ♬*

  • 14:15 is it me or does Amy sounds a "little" different?

  • 14:05 Is-Is that Amy?

  • +so me and my cousins used to do this for fun but instead for better results you need water bottles, baking soda, vingager, and toilet paper. you pour vinegar in the water bottle than put the baking soda in the toilet paper in the top tighten the lid and throw it up in the air. when it his the ground it will explode in to the air

  • Whose voice was it @14:05? Definitely not Amy's !

  • 13:21 Markipoggers

  • 10/10 editiong for tge rocked editor

  • Low key they missed an opportunity to edit Mark's arm exploding under the launch pressure.

  • Rip that there was no "you close?!" During the shaking of the bottle before blast off

  • Its like 2 3rd graders fighting over which bottle they wanted xD

  • Alternate title: filling our stomachs with carbonation to turn ourselves into body rockets.

  • They should use bromine and coke

  • 13:11 WHAT?!?!? Was anyone else FULLY expecting this to FAIL?!?!?

  • I can smell the vinegar from this video and I hate it so much💀😂

  • You're wrong mark plastic wasn't invented in the 1900s it was invented in the 1800s, 1862 to be exact Edit: Alright upon further research i found that although Plastic was invented in 1862 *plastic bottles* were invented in 1947 so you were right considering you were referring to plastic bottles in the vid so 👏🏿👏🏿Another point for Big Brain Mark 🙄

  • amy anytime mark has an idea "are you gonna put that is your mouth?"

  • tighten the fuckin cap.

  • Why are there no Unus Annus stickers in the store?!

  • Tell the editor that they spelled Vinegar wrong. :/

  • I love it when Eef wears nail polish

  • this screams my sophomore year of chemistry lol

  • Honestly, the reason why Ethan probably cut the sticker off was most likely the fact that they did so many chaotic things in the past and this really just came off as Mark doing a bit. It's honestly hard for me to tell that Mark was actually being serious, and he didn't actually point out at first that the bottle was supposed to be his. Not saying that Ethan shouldn't have stopped but I can definitely see why he could have thought this was just a bit. But honestly, maybe this whole apology thing was just a bit too. I DOn'T kNoW, Ok AY

  • ⁴²⁰

  • Plastic:was invented in 1556 apparently Also plastic: was invented in 1900s

  • I was here

  • When I did bottle rockets, mine flew 600 meters in the air

    • @Stephanie Poole no reason...

    • @Stephanie Poole hmmmmmmmmmm

    • @Dexter Mason measured it with a idk what it's called bc this was 5 years ago. Trigonometry. Anyway, why do you care so much?

    • @Stephanie Poole how did u know how high it went

    • @Dexter Mason I wrote this before I watched the whole video. The way I did mine was we put it on a thing and then shot it off using air pressure. We had to calculate the amount of water also to put in the rocket to make it fly as high as possible. So it was very different than what they did

  • The first rocket was made in 1926

  • Oh hey, it's my birthday Unus Annus. Everyone has one. Find yours.

  • Alternate title: chugging two liters of soda for science

  • at 12:37 just look at the reflection in the window

  • im looking back at this, and just realized it was posted on my birthday. lol.

  • Let me just make this clear, dont chug a 2 liter of soda. That's not good for you.

  • “you can see I’ve got a mark on my hand” nice one, Lixian

  • Next video is gonna be an Unus Annus pipe bomb

  • Eef: Bottle rockets were the first things in the sky Mark:What about fireworks that were in the bc? Me: What about the frikin bird pterodactyl’s in the sky?!

  • The first ships in the sky were fireworks geniuses in ancient China

  • Oh I can only imagine what would have happened if they ate mentos after that soda

  • Had "you care about Amy more than me don't you" vibes lol or he was lowkey callimg Ethan a simp

  • I... did not expect... That ending roflmao. I'M DEAD, SEND HALP

  • Am I the only one who zoned out, saw them drink the whole bottle and thought they were going to swallow mentos?
