A couple of suggestions Rather than use a knife to cut holes in the cap and bottle I suggest using a piece of wire and a candle. A heated wire (held in a potholder) will cut holes through the plastic a lot easier and more safely than using a knife on hard slippery plastic. Also if you make the side fins on the side of the sub larger and angle them opposite the propeller angles, the sub will go even faster. Great project!

The prop gave me a bit of trouble, so I've been playing around with plastic water or soda bottles and have made a prop out of two diagonally cut strips from the side of a bottle. Overlap the pieces and either staple them together or use hot glue. Poke a hole in the center and thread it onto the shaft. A sharp bend in the wire will hold it into place. Duct tape might help as well. Cheers! Sarah Hi,
