In the space below, write down any initial ideas you may have about why the liquid oxygen machine is not working.

It's not plugged in. A fuse is blown. Oxygen is no longer present because we killed all our trees. The pressure gauge is broken and all your Oxygen is gas because the gauge says you are at 30 atmospheres when you are actually at 1.5. The cooler is outdated and requires CFCs, which are now illegal.
