no electricity means no fan... one idea could be air, but blowing air is too simple, and i might get points taken off of my project...

Use a rubber band. Wind the rubber band tightly, connecting one end to a stationary object at the front of the boat and the other end to a propeller at the back.

Make your "boat" out of a small piece of flat cardboard, shaped like an arrowhead.
Cut a "v" shape out of the back.
Place in a large pan of water.
Squirt a drop of detergent into the "v"
This will break the surface tension of the water and propel the "boat" to the end of the pan.
This will only work once then you have to change the water, be sure to experiment until you get it just right!

Years ago I had a small boat that used a copper pipe coiled inside the boat so that the two ends of the copper tube stuck out the back below water, the coil was filled with water and a small burner put under the coll. As the water boiled the boat moved forward.

You can pack a small cartridge with baking soda. When it comes in contact with the water, it will start to 'fizzle' and push the boat forward. If you pack it just right, it will slowly be used up like a candle melts. You can't let the whole thing get wet all at the same time. You can take it a step further with vinegar and baking soda, like a jet engine.

clockwork (i.e by winding a spring that makes a propeller go round) or with and elsatic (rubber) band. You would fix one end at the front od the inside and the other to the propeller. You then wind the band tight by turning the propeller.

Steam power!
If you look at the boats in the link, there's two small pipes sticking out the back. One sucks in water, its brought into a small tank with a candle lit underneath it, the water vaporizes and is exhausted via the other pipe which creates thrust.

How about a rubber band attached to a propeller?
