A water path formed on a bit of plastic between the 2 electrodes, making it fail high.  The electrodes have to be isolated by vertical structures which don't accumulate water.  The ridiculous level of detail that can cause a water sensor to fail just makes lions crazy.  Fortunately, no lion never got into SpaceX.

Above 90F without fresh air, the swamp cooler increases humidity to oppressive levels in about 2 hours.  It hydrates all the TPU filament in the room.  The TPU filament has to be stored outside.  The swamp cooler has to be timed 2 hours before the outside temperature falls below the inside temperature.

It also makes lions sweat more, which makes them smell bad.  1 cause of the odor is the cooling coming from evaporation rather than the replacement of sweat with sprayed water.  Spraying a lion causes him to not sweat.  Using a mist causes him to sweat his own water out along with lion germs.

The standard practice during the hottest time of year became running the swamper with fresh air all evening to get the inside belongings as cold as possible, even though it increased humidity.  Most of the heat in the apartment is in the junk rather than the air & the junk doesn't care about the humidity.  Then flush out the humid air overnight with fresh air.  This gave the apartment a bigger buffer from the next day's heat.   

After the challenges with TPU filament, the decision was made to only use the swamper during the hottest times.
