P.S. I love critical comments because they give me a way to improve and fix my mistakes. so thank you, haters.
Step 1: Materials
Like I said, you don't need any rare pieces for this.
16 yellow/gray 5 slot connectors
1 orange 2 slot connector
1 Y connector
2 black/white snowflake pieces
1 blue rod
1 gray 1 slot connector
2 rubber bands
Step 2: Grenade Body
For the grenade body, you take 8 yellow connectors and attach them to a snowflake connector like so, then you do the exact same thing again.
Step 3: Firing Pin
set these aside, because you will use them later.
Step 4: Rubber Bands
Step 5: Putting It All Together
Combine the two halves of the grenade. then, insert the firing pin and attach the Y-connector. to prime it, just remove the y connector, pull out the pin, and chuck it as hard as you can.
