Mlmbd, if by "interesting", you mean total hogwash then I totally agree with you.

Nuclear Catapult Type III?? you damn north americans are so impractical, you always want sexy hi-tech equipment to play with and dont think how to solve the situation with the materials readily at hand...

All you need to fire a thermonuclear hand grenade a "safe" distance is a "Y" shaped piece of wood (or table edge or hatstand) and a piece of knicker eLastic such as those normally found holding the reinforced super-strength gusset protectors worn by old ladies.... the tensile strength of said knicker eLastic is generally sufficient to launch large objects into orbit, let alone a nuclear hand grenade a few miles!!
