>>13072397>>13072416consider the amount of vapor produced from a vape, compared to the amount of water vapor produced when you exhale regular air. one is going to have more molecules than the other, so of course it's going to gush out of the sides of the mask. you will get some escape with regular air too, but it'll be nothing in comparison to a vape. nomsayin?
just in case you still don't understand, AIR is not the same as PG/VG VAPOR. count the amount of molecules in an exhaled breath of regular air vs the amount of molecules in an exhaled vape. here's a hint
x (air) = oxygen + nitrogen + others that compose air
y = air + glycol (this is obviously going to be the bigger number, because it contains more molecules)
so, those molecules have to go somewhere right? the pressure differential between your vape exhale inside of the mask is going to be greater than the surrounding air, so it's going to leak out in a dramatic way. a regular exhale is not going to cause such a dramatic pressure differential (and lets be clear, this is not a HUGE pressure difference, but it's enough to see the effect in action) and it won't spew out as much as it would like the vape vid.
tl;dr more molecules = more pressure, less = less pressure. yes, there is a chance water droplets/particles that have the virus in them can escape, but the risk is reduced, because you have something that can catch said particles.
