Science Buddies: "Ask an Expert"

i have to make a submarine that floats on water then sinks then rises and after that it has to move to the side... i have seen some examples.. but they dont really help. i need some sites on how to build this kind of sub

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!

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!
Geoff.
