Homemade Boat? - homemade boat motors
Who knows how to make a houseboat or other help? I need a boat "model" which is about 1 m by 1 m of 8 inches for the school and must be fed, no motor or other electrical device .... or CO2 cartridges more ... I have seen balloons boat, but my boat is faster and stay in a straight line. Competition is so I can not use a candle ... I thought about using a baking soda and vinegar into the bottle with the gas, and ensure that these ... yes ... thnx very difficult to determine in advance!

I think your idea is good, it must prove, but it is promising. The only problem is that you think you are in the vicinity, as follows:
put the soda in an adjoining room with two run-off, a burden is the production of gas and the other is the entry of vinegar. Stop the vinegar in a separate bottle, the bottle in relation to the chamber with a tube with a tap or a rubber hose that you can and push the flow of vinegar and its gas generator
Try putting a rubber band on one side of the impeller. Perhaps a steamer elastic, depending on how it will fulfill its three-dimensional requirements. Any attempt to use a propeller spring will be difficult, because the screw creates a yaw varies according to speed. When the winds of spring, decreasing the rotation, so that any adjustments to preset rudder compensation would be necessary or remote computer.
Start early and play. I see in my head, how to manipulate the keys to the paddle or rubber bands.
