this k'nex frag grenade is based off an idea by the inventor. the link to his grenade can be found here:
the only parts that detatch on impact are the red pieces. the rest of the grenade stays intact, making it easy to rebuild.
Step 1: Materials
you will need:
2x small green rods (NOT PICTURED)
10x red connectors
2x blue connectors
1x blue rod
2x white "snowflake" connectors
Step 2: The Basics
attatch the two blue connectors to make a ball.
also, attatch a green rod to each white connector.
Step 3: Add the Fragments
add the red connectors to the white connectors, as pictured.
no rods should be used to connect the red pieces.
Step 4: Putting It Together
first, attatch everything as pictured.
then, simply attatch the blue rod as pictured. this will act as a handle you can use to throw.
Step 5: Throw It
