Like Archimedes and testing the King's crown for purity?
 
50 miles over 2 days at River Neck Acres ATV Park in Florence SC. Stayed overnight at one of the unfinished cabins, just brought all my camping gear sans Tent, and used a propane heater and predator 1400w generator.

Did take an accidental swim when it fell into a hidden rut under water and had to drain a gallon of water out of the belt case...

The Archimedes method is a little different. You use a hanging balance and first weigh the core then use a tub of water brought under to submerge the core and record the weight which drops according to Archimedes' Principal. Difference in weights = volume of core.
