Wood arrow penetrated the coin.
Apparently, in this picture this arrow penetrated the coin even though the head is bigger than the hole of coin.
This arrow is made by wood. This wood arrow is not soft, can not be bend, can not be twisted.
It looks like impossible to remove arrow from the coin without breaking the head of arrow.

How this could be happen.?
Manufacturer says there is a way to do this at your home.
That is not impossible. That’s why this is hot selling item here.
But nobody knows what is the right answer.
But Soon you will know.

Think, think, think and there is an answer.
Hint. You need cold water, hot dryer and 30 minutes.
