Waste Products Test

Gas-exchange experiment

Lifing things should breath out some waste gasses.

No radioactive labelling in this one.

The experiment:

1. Get some regolith.
2. Moisten it with "soup" containing plain hydrocarbon molecules.
3. Look in the gas given off to see what gasses are made.

Control experiment:

• Keep feeding it soup.
• A chemical process might make some gasses, but when the reactants are used up the process would stop.
• Creatures would keep growing (if they like the soup) and keep giving off gasses.

Result: Some O_2 and CO_2 seen at first but more soup did not lead to more O_2 and CO_2 production.

But maybe the creatures died (again).

So it still appears that the regolith is just chemically reactive.
