I deal with acid gas infrequently but it would be something nice in the long run.

I have a funnel right now but its stem is much thinner, so my powders often get stuck.

Sulfuric acid is an extremely versatile catalyst and reagent. I could make all sorts of things ranging from sfl-cented oils to flash cotton.

Bromine looks really cool to make, a bromide salt would be the easiest starting point.
