Right so first thanks to viper who first linked a video from a gaming youtube channel to the epic spork video!
I went to try it out with a couple of friends and found there were a few lapses in the video. If you are a n00b to glitching or find when people leave important info out of a tutorial that you get stuck read on. We played 20 rounds without getting it to work and I finally looked at the many comments and saw people saying ITS FAKE etc etc etc till I saw one lone helpful comment which made Me question the brains of the person making the video tutorial.
Note after testing you have to do this every time to get your golden spork
STEP 1. Complete the plane parts and fly to the bridge and return via the electric chairs.
a) You also need to do feed the beat at this point - feeding the 3 hell hounds zombies until they disappear leaving a red mark on the wall and allowing you to collect the tomahawk from the room on the way to the docks in the tunnels. Every person in your party can have a tomahawk. Cool weapon but useless compared to the spork minus getting perks and such.
b) Have everyone hit the box till someone gets the acid weapon this will need to be upgraded using the parts around the prison. It does not require the additional pack a punch but does not impact the easter egg from working. One person MUST have this gun upgraded with acid.
YOU CAN NOT MAKE THE SPORK UNTIL YOU HAVE GONE TO THE BRIDGE AND RETURNED.
Step 2. When you land back in the prison revive yourself and run up the stairs to the afterlife box near the sign that says MICHIGAN. There is two cells to the right of it the one on the left has a poster on the wall. Now you can use the tomahawk to rip the poster off the wall to expose the afterlife symbol.
Step 3. Have a member of your party go into afterlife and go through the hole in the wall where the poster was they will have to go up a bit and then will see a concrete spoon shaped hole on the ground have them zap with right trigger the spoon or fork which is to the right of the hole in the ground. DONE.
Step 4. Go to the cafeteria where the acid trap is the window at the back on the left side you will see a three tier white trolly on top of which after the return from the bridge will sit the second utensil fork or spoon. Aim with your tomahawk see the red flash and hear the sound and you have it.
Step 5. Head upstairs from the back window to the stairwell on the right up to the infirmary. There is a room with a single bathtub full of blood. Hold x on it and see a spork floating round in the blood… You can not get it.
Step 6. Head down to the shower room where the person with the acid gun now needs to shot about one round of zombies 3/4’s of them at round 18 was what it took with half the zombies spawning in there. When you have killed enough you will hear the good old mystery box saying hahahahahah GOOD BYE.
Step 7. Get your party back up to the bath tub in the infirmary. Have each person hod x on the bathtub a zombie hand will rise from the blood offering THE GOLDEN SPORK. Take it and kill the zombies 
Every single person in the party will now have the spork. It is a one hit kill to round 44 so far still testing will update again tomorrow we had to finish our game for the day.
We also believe you can go back in when it is completed just like the tomahawk do your first early round in the shower and collect it. I have to go test it now but will let you all know shortly.
This is a super over powered weapon compared to anything else and also makes high rounds ridiculously easy so no idea how long till they patch it so enjoy it while you can!!
If you are at a higher round in the shower room and struggling with the acid gun have another team mate get in the shower room glitch and crawl to them to be revived if you go down. The person with the acid gun will be pushed out of the glitch when they shoot. The zombies will pile up there though allowing someone to sit in the washing machine area blasting them.
