Step 3 Nose cone and Fins

Glue the fins on to the bottle vertical with the bottle. (in other words, the normal way) Use the glue gun for this. Squeeze the glue on to the flap of each fin and attach to the bottle. Repeat this step for all fins. Finally, reinforce the fins with more glue to create a watertight seal to the bottle.

Next, it's time to make your nose cone. Take a plastic cup, and cut down one side of the cup until you reach the bottom of the cup, then cut the entire bottom of cup out. Then, curl the cup to form a cone shape and glue. Finally, glue to the end of the bottle and tape to ensure that the cone is attached. Use pictures for help.
