Here is your spelling/grammar lesson for the day. We are going to learn the difference between threw and through.
Threw is not complicated.
Threw (verb) To propel through the air with a motion of the hand or arm.

In short, the difference seems to be how something was propelled. If someone actively flicked, propelles, or casted something, you use 'threw.' My hand actively propels the baseball therefore I threw the baseball. However, if nothing propels the entity, but rather it propels itself, then it is 'through.' I walked through the park. No one pushed me. The play last through the night.
