I was fooling around on survival and decided to shoot a head when the arrow stopped in midair. Then I walked up to the head and picked up the arrow.

What I expected to happen was for the arrow to come in contact with the head.

What actually happened was the arrow stopped in midair.

1-Place a Player Head on the wall
2-Get a Infinity 1, Flame 1, Punch 2, Power 5 enchanted bow
3-Shoot an arrow at the head
