Step 1: Materials
You will need 2 grey one-slot connectors, one grey rod, and either 57 blue spacers OR 19 grey spacers.
Step 2: Putting it together.
One: Get this
Two: Add one grey one-slot connector to the end
Three: Add the blue spacers�ver spacers
Four: Add the other grey one-slot spacer to the other end of the rod
Step 3: Using the Grenade:
Take off one of the grey one-slot connectors.
Hold the grenade by the other grey one-slot connector.
Flick your wrist, or make a throwing motion toward the ground, but do not let go of the grey connector.
If you do it correctly, the blue (or grey) spacers will hit the ground and scatter around.
You can use different sized rods with the corresponding spacers, or just use less spacers.
