Well, it could make a gas with the appropriate reagent, i.e. an acid.

Explanation:

And a suitable acid would be hydrochloric acid...

#HCl(aq) + NaHCO_3(s) rarr NaCl(aq) + H_2O(l) + CO_2(g)uarr#

And sodium bicarbonate would even react with vinegar...a reaction that has been known since biblical times...

#"As vinegar upon nitre, so is he that singeth songs to a very"# #"evil heart."# #"Proverbs 25:20"# (and I think the author of Proverbs has confused potassium nitrate with sodium bicaronate).
