|Assembled Submarine with ballast can in place.|
|Showing detached ballast. Ready to surface Sir!|
The model is of a Submarine that will submerge and, on touching bottom, release a can of ballast an then rise to the surface. It has been quite an easy build so far, although I've not yet gotten onto making the mechanism for dropping the ballast can. Now, apart from letting the children have it (madness, surely!), what ever shall I do with it???
