Step 2: Whatever Its Called

Picture of Whatever Its Called

1. cut out a 2 in. by 2 in. peice of cloth.
2. make 2 holes in the corners but dont make them to close so it rips when you put the rubber bands on.
3. make 2 holes in the middle of the cloth( all holes are shown where to cut them on the picture, the holes are repreasented by gray dots.
4. take a peice of string and loop it threw the 2 holes and tie a grey connector to the string and connect another grey peice to the first grey peice.
5. loop a rubber band in each corner as the picture shows.
6. connect it to the frame like in picture.

GARRGGGHHH, Can't there be a filter that removes KNEX projects from the "Explore New Projects by Date" button? Don't get me wrong you KNEX people, hey have fun, but man, it seems like half of the instructables each week are for some knex toy or another. Maybe start up KNEXstructables.com or something. Fer realz! But I still love you peeps.

Sweet, it reminds me of a game my friend had a while back, the one where u wet a tissue and try to put marbles on it with out breaking it. Looking back it seems kinda retarded now. But your gun thing* is AWESOME!!!
