I no longer think that will work.

However I'm still sort of interested in ways to reduce/absorb the heat of hydration of SO3. Instead of dealing with strange chemicals the following rxn seems interesting:

CaSO4*2H2O (plaster/gypsum) + 2 SO3 >> CaSO4 + 2H2SO4

with significantly less heat released than the reaction with water, but still a lot. How to perform this though?

The difficulty is not in producing SO3, which happens by simply heating bisulfate, but in capturing it without destroying it or killing the experimenter.

Nice! Finally a way for people with little equipment to produce sulphuric acid at home. Thank you.

Codyslab did a video on this recently and got me thinking about improvements. It would seem to me that the dissolution rate of SO3 is limited by the surface area. Why not add in one of those piezoelectric humidifier elements to get some good spray going.
