So, it turns out that potatoes make better bricks in space than human blood does.
How do we know this?
Well, scientists at the University of Manchester in England demonstrated the effectiveness of potato starch as a binder in space bricks, and they're calling the potato starch StarCrete.
In the same study, they also ended the age old argument about whether human blood is a decent option for brick mortar by making some bricks using human blood.
Charlton Heston's Moses called it on that point: "Blood makes poor mortar."
Not only did the potatoes make better mortar than blood, astronauts said they would prefer using potatoes to make their bricks over using their own blood or urine.
Space potatoes also weigh a lot less than traditional concrete, which helps with getting off the planet.
On the downside, the potato concrete does still need a specific salt compound, magnesium chloride, which the scientists say can be extracted from Martian soils, but if not, then it can also be found in human tears.
If they need tears, they better take a woke influencer and a subscription to The Babylon Bee with them.
