Step 4: Loading and Firing

Picture of Loading and Firing
To load clip a normal shot(no rings) or a exsplosive one (with rings) into the yellow connector. Then pull back the shot like cocking a gun the slip your finger off. If it does not fire try adding more rubberbands.

You can also clip a white rod on the yellow connector and put any slip any knex pieces with a hole and fire.
