Excavator loading tar - GIF

Water must remain separate from the tar as it would if you mix water and oil. It is was trapped in pockets in the tar, it might explode when the tar is melted.

I find it fascinating that the tar falls out as a clump. Then before the bucket gets back with the next load the previous one has "flowed" seamlessly into the mass already loaded. Tar is weird stuff!!!
