use simple science tools. if you rig something up in the back (like a water mill) say going down, then put one on the front going up. This will capsize it and cause it to sink. and then have a switch to reverse the motors.


You'd need)

two c batteries
4 motors
lots of popsicle sticks
glue gun


use your imagination... although.. you've prolly already had to do this.. it's kinda old.. locka?
