There was a Vietnamese uprising against the French in 1916 where the Vietnamese tried to use potions to make themselves invisible and plant bombs against the French.
https://en.wikipedia.org/wiki/Phan_X%C3%ADch_Longhttps://en.wikipedia.org/wiki/1916_Cochinchina_uprising>Phan Xích Long, also known as Hồng Long, born Phan Phát Sanh (1893–1916), was a 20th-century Vietnamese mystic and geomancer who claimed to be the Emperor of Vietnam. He attempted to exploit religion as a cover for his own political ambitions, having started his own ostensibly religious organisation. Claiming to be a descendant of Emperor Hàm Nghi, Long staged a ceremony to crown himself, before trying to seize power in 1913 by launching an armed uprising against the colonial rule of French Indochina. His supporters launched an attack on Saigon in March 1913, drinking potions that purportedly made them invisible and planting bombs at several locations. The insurrection against the French colonial administration failed when none of the bombs detonated and the supposedly invisible supporters were apprehended.>The organisation and motivation of the uprisings were unclear, since many different organizations of Vietnamese revolutionaries with different ideologies were involved. Some were supporters of the mystic and geomancer Phan Xich Long,[1] who had claimed to be a descendant of the boy Emperor Hàm Nghi, who had been deposed by the French for attempting a revolt with the aim of securing independence some three decades earlier. Long had been imprisoned three years earlier after declaring himself Emperor and attempting to storm Saigon with the help some purported magic potion to restore the monarchy. Long's supporters sought his release from jail.[1]
