Figure 3. An airtight jar of weevil-infested seeds (A) is flushed with CO2 generated in a bottle (C) containing water, yeast, and sugar. An optional check valve (B) ensures one-way transfer of CO2 into the jar of seeds. As CO2 builds up in the seed jar, gas is exhausted through a tiny hole (A) in the lid. Source: Tim Motis
