There is something off about the weight. Muscle is only slightly more dense than water. So 20 pounds would be about 9 litres of tissue by volume.

This looks like maybe 3 litres at the most including the enclosure and liquid it's submerged in.

Edit: ok, so other articles say that the whole urn is 20 pounds. Makes a lot more sense https://www.scmp.com/news/world/americas/article/3189818/emp...
