Seeing as your suit was radioactive ("wearing radioactive nuclear protection suit") You slowly die of radiation poisoning. As you die, I use a Teleporter/Time Machine to take the popcorn from the next user before they even post their message.
2.3 BILLION Years Later
I put the popcorn in a ship capabale of FTL travel, with an infinite fuel source of course, 2.29 Billion years ago. It could be anywhere by now. I dont even know where it is. (Why would I want it? I dont like popcorn)
im on the hull of the ship, FTLing with the machine. its mine now.
with extra box. no wormhole travelable, warpable and teleportable. 1E+5000T shock proof alloy (if 1 cm) and can hold up to 1E+4000 (1 with 4000 zeros) celcius. 25X25X25 MegaMeter box. 12 MegaMeter thickness in every side. im inside the box with kydonshadow's ship.
AAAAAAND any type of power wont work.
Seeing as conventional strategies won't work, I fire my antimatter cannon at the box, the matter-antimatter reactions slowly eating a hole through the wall. I then travel through the hole to reach KydonShadow's ship, which I sneak aboard and then steal the popcorn. I finally place the popcorn inside a hollow sphere made of strange matter. Any attempt to steal the popcorn will result in the popcorn being irreversibly converted into useless strange matter.
(3 billion years... would the popcorn be a bit moldy?)
I give the strange matter some courses on how to interact with other matter, and it becomes normal matter. I break through with a jackhammer, and take back my popcorn.
I create a pocket dimension with a quantum enstranger and put the popcorn inside. Seeing as No one else knows what a quantum enstranger is, I destroy it. In the last few seconds of the wormhole's existence, I throw the pieces of the enstranger into it, making it so that no one can recreate it. As soon as it closes, I wipe my memory and live a new life with the name Johnn Morrison.
I take it out of the volcano.
====================================
I burn the popcorn, so now it's on the air, good luck getting it.
You destroyed the popcorn, but eventually rearranged themselves to their normal form. (they're all nanobots)
And, of course, got it.
------------------------------------------------------------------------------------------------------------------------------------------------------------
I place it on the crater of Mount Vesuvius, Italy, in a certain time whence it erupted.
Don't worry, the bag is completely heatproof.
I manage to teleport it to me just seconds before the volcano explodes.
I throw the bag onto a neutron star, where it is flattened and spread in a uniform layer around the entire surface area of the star due to the star's gravity.
It was a loooooot of poopcorn. The added mass is just enough to push the star over the limit and turns it into a black hole. I on the otherhand have a small whitehole generator. The poopcorn comes through, and it is now mine.
I [censored] in the popcorn, making it actual poopcorn. Go ahead and take it if you want, you sick dirty freak.
