It's enough for a little military mission in the pond of my neighbour this weekend !

Looking for information about setting up a boat with a jet engine system.

I'm building a submarine however i'm a bit stuck on what colour it should

I'm just building a Stuart D10 steam engine - it is quite powerful, OK

one huge 1? So long as there is 3 different batteries.
Thanks
Michael

Would something like petroleum jelly work? Or is there something that is
better?
