The Cuban Altomicular bomb. It was a bomb designed by Cuba for war emergencies but when they tested it in the desert, all that came out was a sound.
Second Answer: The least powerful bombs would be the hand grenade, some of the land mines have low volatility but some are capable of damaging tanks and other military vehicles and some plastic explosives are small and do not do the damage of larger bombs.
You can consider the hand grenade the weakest since it can only injure people within a 15 to 20 feet radius and has more concussive power than power to disintegrate or blow people apart.
The Cuban Altomicular bomb would be considered a dud and not a useful bomb as the grenade is usable.
