Put a “HOLE” in the barrel, its weight will automatically reduced.
or put a fire in it 😛
he kept fire or hole.
He removed few gallons of oil and now barrel is filled with AIR+remaining oil. Hence, weighs less.
He puts something into the barrel with a lower density than oil. The oil will spill out of the barrel and the whole contraption weighs less than before. A big block of wood would do the trick.
