  • what about the back room freezers?

  • Bruh theorista died on impact of the virus....

  • Honestly it's not worth it. Just become one with the zombie aliens.

  • !gr8 episode .I watched twice because I wanted to show it to someone!

  • Plot twist: Theorista was a mad scientist staging the invasion, and was the one to tell Evan to stay inside Stater Bros. as a rendezvous trying to find out the maximum length of time you can live inside a grocery store. Extra Plot Twist: Theorista was Matpat this whole time. Matpat in our current timeline was so unable, and tired trying to find out the exact maximum time before you would starve to death, so he resorted to creating a time machine called the "Epic" from his past research on a 10 year old video on time travel from the game "Chrono Trigger" To conclude his research in an alternate timeline, where then he can bring his studies back to our timeline to then make this video here. On this channel. Yes. Because Evan left a comment on Matpats channel, he has created a catastrophe in a whole other universe.

  • Years

  • Evan and Theorista. Name a better duo. I'll wait.

  • Not long first few days "ok I finally got everything done it's all organized this will be easy this is enough for months maybe a year" nearly a week later "oh god what did I...its almost gone"

  • id probably die in a week

  • yay minecraft lol

  • Food theory idea : What’s the minimum amount of food a person can survive on and be “healthy”?

  • my grocery store has an entire shelf of a ton of different seeds so

  • what about ramen?

  • 5:15 what about ices?

  • eh I'll watch this video later, let me try this beforehand

  • Oh my god I'm hungry

  • Even after watching all these, my dumbass still doesn't remember all the procedures to survive that long.. Evan dang smart and resourceful with his survival info huh

  • Ok yeah but what about water I doubt there’s 25+ years of water in there Matt pat

  • I'd probably last a few hours before the cops show up and arrest me...

  • Most grocery store vegetables can be regrown if planted. If he used some for planting and some soil (a lot of grocery stores have soil) and compost helps makes them.

  • I actually have daydreams about a scenario like this but with all the utilities still working and some way to get garbage out of the store so it doesn't end up filled with rotting food. Ideally this would take place at a Walmart so you would have just about any non food item you could possibly want but the regular grocery store would work too.

  • Ha! Love the Bendy's instead of Wendy's and the Freddy Fazbear's instead of Chuck-E Cheese's. And a Nyan Cat! Cute!

  • To all the people who didn't watch or understand the video or are just going by the title and say why didn't he break out or go out the open window it's because he isn't locked in and trapped in the scenario the video gave. He locked himself in on purpose to hide from the alien zombies. Why the zombies aren't noticing any smoke or smells or noise from that open window or going in it after him I don't know.

  • ngl this kinda sounded like a math problem in the math text book around minute three

  • wouldn't the most important things be like, weither the supermarket has a deep freeze, or if electicity is going to last forver? because then you could feeze all the meat

  • This video doesn’t work because he has based it all of people needing 2000cals a day what isn’t true. That’s the recommended not the needed. You can survive in a lot less

  • I love this theory!!! I've said for years that if a Zombie Apocalypse happened I would make the grocery store my home! I even know how to can and preserve foods just for that reason! I have no complaints with this theory although I would sprinkle in a few extra details. Does the store have any backup generators and how long they would last? Could the sprinkler systems produce any type of drinkable water? (probably not but filtration would be nice) Does the store have a take-out section where you could buy cooked food? (Besides more food to store and actual cooking supplies, some industrial freezers that might deter pests.) And lastly, what about pests? What measures could be taken to deter rodents and creepy crawlies, or is it better to attract animals to hunt for food instead? Yeah I thought waaaaay too into this!

  • Food theory idea: what would be the best place to go in an apocalypse type situation for food besides making it yourself.

  • Hypothetical person looks like berleezy

  • alternate message - you eat approximately a whole grocery store worth of calories when ur 63.3 years old

  • Theory idea: how long can you survive on on the ISS was food brought from earth and food on the station.

  • I learned about some of those foods being edible for decades from Steve1989's videos (where he's had candy, cookies, peanut butter, etc from World War 2 rations that were still fine).

  • Wait wouldn’t most grocery stores have potting soil and containers and stuff like that?

  • are u counting the front of the grocery store only to like the storage room. to like the back. where your not supposed to go

  • You are for getting however that you can't eat dry dog food as well trust me I've done it just don't go after the cat food that's stuffs nasty

  • 4:40 the mist was right there

  • That's awesome i like that good jobs

  • if i had a steaming iron i could last til the food ran out so probably a year

  • Honestly, I want to do this

  • Well that’s if we take out his mental decline due to lack of human interaction. By 6 months most ppls social skills and mental would be obliterated.

  • Step One: Make a compost out of the spoiled goods. Step 2) bury potatoes in the compost to make more potatoes. Step 3. Become potato person.

  • He can reuse the cans and can the potato’s he grew for the past 63 years

  • The Martian type beat

  • There adding up all these years of food like he gonna live to be 100

  • So he didn’t even step out the entire time what

  • Dam theorista must be coming from like china

  • Short answer; until all the food expires. Edit: Nvm, after watching the vid I realized that you'd die from boredom

  • Food theory idea: is cereal soup

  • Downloading this just in case 👀

  • How long could you live in a fully stocked food truck

  • I'm almost positive Even wasn't the only one to ask that question on one of your videos before.

  • i want this to be a video game.

  • 4:44 Was your creativity going into debt because of rent?

  • I'd say grab some tools and tear up the floors and get to the soil under the store to get more soil that can be mixed with compost, plus no grocery store shouldn't have just the soil, but some seeds as well, to make grown food more varied

  • so since running water isnt a thing here, evan is shitting on buckets for years?


  • I see salami I click

  • what if you were locked inside kfc though

  • 1 kcal = 1000 calories please. there's a huge difference...

  • If you gets stuck on kfc food how long can you eat it until you can’t anymore

  • *Break open the door if I could.*

  • Apocalypse happens Farmville players: my time to shine!

  • how long can you survive in a SUPERSTORE

  • oh awesome my name is luke too

  • Just want to say, plenty of stores have portable gas cookers for camping and that'd probably be better than actually making a fire in the store

  • This has already been covered by the channel Meet Arnold a year ago.

  • Interesting

  • 5:11 You have Canadian milk in the U.S? I mean... Not horribly surprising, I guess, but I'd figure they'd use an American brand...

  • So.. SCP-3008

  • Should not have watched this in Ramadan.

  • what about animals such as rats they might bite open certain thigns and make them rot faster also nice vid man

  • There are two guys here in my city that would eat the whole store and would still be hungry😂

  • 12:21 techno would be proud

  • My shop near me has about 12-13 bags how much soil would you need to live

  • 😐QUESTION: If the ISS was completely cut off from Earth and it's crew had no chance of return, how long would the crew be able to survive and maintain power?

  • If you look closely, the thumbnail and the title closely resembles a Mr Beast video

  • Watched this while stocking shelves, and I had one question: did you guys only account for the items on the floor, or the attached warehouse as well? I mean it wouldn't really matter to the final results, but it would make the farming a bit easier as you wouldn't have to move any shelves, just pallets with the handy pallet jacks.

  • You will actually die within 2 years if you consume their food

  • My friends: Wow impressive Me: *writes everything down*

  • no making food dehydrator from a light bulb fan and cardboard box?

  • My humor is so broken that 7:37 had me dying of laughter

  • Did you take into account any food stored in the back? Also, though edible, I don't think the food in the last two periods would be nutritious enough to keep Evan alive.

  • what about the open window he could climb out or break it using a mop or something

  • How cool of an area would this be in fallout

  • He, alone, can't possibly accomplish all that in 1 day.

  • Lol as a farmer I feel even more confident to survive in a food mart lol

  • This is my first video. This is fun

  • Was really hoping the book Monument 14 by Emmy Laybourne would be mentioned. 14 kids (ranging from 5-18) are all stuck in a grocery store due to an apocalyptic situation outside. Great trilogy

  • Yeah but like.... the dried beans can be planted and so can the rice.... so can the fruit seeds. Also often times stores have seed packets for vegetables. So really if you are not just expending resources, you could live there indefinitely. Also you might have to dig a well.

    • @Jaded Phoenix assuming you’re locking yourself in a store usually that implies you cant go there

    • @Kenji Dayan roof

    • You’re still gonna need sunlight

  • This should be a Netflix series

  • Why not just use a Walmart

  • “All utilities are out of order“ Evan: I got to poop

  • Forever.

  • Wouldn’t you be able to break the ground to get that dirt for crops I mean it’s still in side the store.

  • For that first part you’re very generously assuming that the average person is smart enough to build a fire that won’t burn the whole place down and also smart enough to know how to DEHYDRATE FRUIT over an open fire


  • This was awesome

  • But you could stay alive longer because you don’t need the recommended You just need the bare minimum Enough to survive

  • Idk I’d star dehydrating and prepping for the first week and get everything and set like idk ten or more fires yk. Also wouldn’t you go insane pretty easily without out to do all day
