To have a pool that doesn’t immediately devolve into a slime puddle, you have to have a ‘floaty poison holder’ to kill all the space germs.
Then you gotta be jackin around with it adding more poison, (naturally) have to chuck it out into the middle of the pool while putting just enough spin on it that it lands upside down, blasting the lid and contents into the pool.
…which is one good reason to own a 3D printer!
