The boy wrapped the slab of meat in the silver paper then grilled by 30,000 matches.
The boy bought a slab of 5-kg meat then wrapped carefully in silver paper.
30,000 matches were put neatly on the big stray and the slab was put above them.
Just one time of lighter, the whole 30,000 matches got fired.
The matches soon burnt down.
When he opened the silver paper outside, the slab of meat was underdone, maybe because the slab was too big, the outer layers of the meat just became well-done.
