oooooohhhhhh. that must be one hell of a big balloon up there!

@Calbeck  
It’s sort of like when you make a film, and you just think of something for convenience solely as a means to advance the story passed a certain point.

@Background Pony #0CF0  
for the creation of exceptionally large plots yes

@the-furry-railfan  
well, i was wondering where that came from. the more you know i guess. lol

@the-furry-railfan  
So, it’s just a plot device.

@Background Pony #0CF0  
It’s a fictional heavy element I’d come up with years ago to have a bit of fantastical science alongside inflationy shenanigans, designed to take advantage of the fact that two common radioactive decay particles (Alpha and Beta) are the building blocks of helium atoms.
 
For my purposes, it’s just either a gas or a metallic solid that can be used to create very large amounts of helium in various places, typically ponies but occasionally also (with the help of a filter as seen here, as the gas is normally inert and will not become helium in non-organic containers) large balloons.

I looked up P-235, and all I got was pictures of tires, and planes. I guess you pump up tires and planes fly, so…the material is related to that?

@BobbySeas  
i would say the balloon is playing with him

Now that ain’t how tension forces work

@Calbeck  
That’s one small step for ponies, one giant balloon for Bobby to play with~

sign me up! looks like a fun ride :D

And that’s how the Equestrian Space Program was made!
