I have to make a miniature submarine, no bigger than the average purse, that floats in a 30 gallon tank, then sinks, comes back to the suface, sinks once more, and then comes back to the surface again. I can not use any chemicals or anything that will change the water colors or any gas. I am also not allowed to touch the submarine after I set it in the water. I can not use any remote controlled subs or anything like that and it has to be homemade. I need lots of help because the only one I can think of I have to use a straw or squeeze the bottle...which I am not allowed to do. Anyhelp would be wonderful. Thank you.
