Ostry’s son Mike showed his father some calculations. He had counted the individual boards and timbers in the barn and estimated that the barn weighed approximately 16,640 pounds. He also estimated that a steel grid needed to move the barn would add another 3,150 pounds, bringing the total weight to just under 10 tons.
The next step is to gather about 350 of your best friends and invite them to come lift your barn. The video shows the result.
