Barium sulfate is an aid in visualizing the contents of the gut through MRI.
Do not do any experiments with this stuff. Some people are allergic to it and it can cause death within a matter of hours for these individuals.
This visualizing agent is used only when people have a very serious ailment, such as a life-threatening bowel cancer or something like this.

If BaSO4 is not safe to ingest, then you will kill the 10 healthy volunteers on which you experiment. Rest assured, however, that BaSO4 is so insoluble in water that patients are given slurries of it to drink so that it shows up in x-rays to reveal abnormalities in the digestive tract.

It increases the density of the fluid.
