Here is a model I built a while ago. There is a bit of history that goes along with it.
It is the old Nichimo 1/200 scale kit that I built as a kid back in the 1970s. Being a kid, I did it using the electric motor power option. I actually ran it in the pool a lot, but could never get the battery cover to seal up properly, so it sank a lot. Eventually the motor seized up tight and it just would not go any more. So I installed a firecracker in the battery compartment and "depth charged" it in the neighbor's pool. BOOM! It was quite spectacular! Some pieces even landed on the roof. I collected all the parts I could, glued them back together, put everything in a plastic baggy, and forgot about it.
