A device for facilitating a chemical reaction while submerged in a liquid catalyst includes an upper member, a lower member, and a dissolvable member disposed between and ultimately enclosed by said upper and lower members such that upper and lower chambers are formed having substantially equal volumes. The upper chamber may receive a dry sodium chlorite and the lower chamber may receive a dry acid mixture. In order to keep the device submerged in the liquid catalyst, an inert ballast may also be added to the upper and/or lower chamber, such as glass shards.
