Water Rocket

Step 4Glue the Fins

Now, if you plugged the glue gun in earlier, it should be hot by now. If you didn't, you'll have to wait for it to heat up.

To glue the fins on, simply choose a side of your fins that you want to glue on. (Use the same side for all of the fins.) Then, put a good bead of glue on the fin and press it onto the duct tape. Make sure that the fins are all the same height and that they are parallel with the rocket. If they are tilted, the rocket might spin.

Duct tape might work, but I just used hot glue because I could hold the fin in place while the glue hardened.

Do you put the duct tape on to keep the hot glue from melting the bottle? Or does the duct tape have a different purpose?

Oh, I see. Nice idea. A while back I tried to make one and the hot glue melted and disfigured the plastic. But my glue gun is a high-heat glue gun. I figured I'd eventually buy a low-heat glue gun and try again. Maybe we'll test the high-heat glue gun with the duct tape to see if that will protect the plastic. Thanks for a simple and straightforward Instructable.
