Sublife Mini Rechargable Submarines

Sublife – A water-activated Submarine!  Simply drop the sub in the water (great for pools, hot tubs AND bathtubs!) and watch it automatically start, it will descend up to 2 meters, then it will run straight for about 40 seconds, then pause and ascend to the surface (like a submarine) for about 20 seconds, then automatically descend and start the process all over again! Various designs.
