hi!

Here are some sites where you can learn to build a sub:

1. http://www.submarine.freehosting.net/
2. http://inventors.about.com/library/inve ... marine.htm
3. http://www.franske.com/blogs/bensblog.p ... roject#c90

I hope that these sites help! :D

Woah! Sounds like a lot. Now does this usb have to be automated: must it perform all these functions on its own, or is radio controlled? Please elaborate. Hope ya have fun!

Hi there,

I remember having something like this when I was a kid! The submarine was not technically advanced by any means - it simply employed baking soda tablets and vent holes. It worked like a charm! :)

The lateral movement, however, will be interesting... Do you have any ideas as to how you might do that? Please let us know once you have had a chance to check out those earlier websites, and how you think you might approach this challenge.

Good luck!
