How To: Build an impact cracker with a penny

You will need a penny, a roll of caps, and a seloptape to make an impact cracker with a penny. First take the roll of caps and rip off of the beginning and end parts that are without caps. Then divide the roll of caps in half and take one half of the roll and start folding it in half all of the way from the beginning to the end. Then take your penny and wrap the caps around the penny, the penny should be off center. Then wrap your wrapped penny in seloptape to finish. Make sure that all of the sides are covered in the selotape.
