How do I make a boat so that it floats for 10 seconds, then sink it without touching it, and then bring it to the surface, again without touching it?

That is an interesting proposition. I am not sure why you want have
something float for 10 seconds then sink, but I have some ideas. If you
created a boat with a hole in it, then filled in that hole with
something which either disolved in water or melted away, then you would
have a boat that would float for a while and then sink. As for a
perfect 10 second timing, that is hard to imagine with out more
advanced equipment. Best of luck!!!
