can you just have the gas through a contanier of the chemical that takes away O2. the have the packets in beef jerky bags. if you get alot of the chemical it might that out all of the O2 that is being produced. also there is another chemical that was used is submarines that takes out CO2. there is also another one that navy seals used in there rebreathing dive suits. so they produce no bubbles. just throwing it out there.
