Wasp Cards
these can go through about 2 sheets of paper sometimes with a good rubber band and seem slow but really hurt
Supplies
you will need a regular playing card, rubber band, and pliers(optional)
Folding 1
fold the card in half twice until it is one forth of the regular card
Folding 2
now fold it the "hotdog way" again. some ppl stop here but it's way better if u go one more
Last Fold Almost
now you might need pliers for this. after you fold it, just put some tape around the edges so it doesn't fall apart when folding in half.
Might Rip at Tip
now just put the middle up to a table or something and bend it. it might rip and this will mean you folded well. if so, just put some tape at the tip to hold it togeather :)
