How Do You Make A Cheap “Flash Grenade”?
This is an easy to make, inexpensive “bomb” that makes light and a jet like sound. It can be used to relieve boredom, or perhaps as a special effect in movies. • Place a soft paper product (Such as tissues or toilet paper) on a flat surface. • Hold a sparkler above, bending the metal rod so the grey powder falls onto the center of the paper. • Roll the paper and twist one end, so it does not allow the powder to escape. • Put a fuse in the open end, ensure it touches the powder and protrudes from the paper as well. • Twist the open end, so it clings to the fuse and does not allow powder out. You have now made a “flash grenade”, although it’s more of a bomb.
