Here is a new grenade I made that has a pin. Pretty good for KNEX wars. A rubber band holds it from blowing up and when you pull the pin out it pulls off the safety band, and it's ready to be thrown. It's pretty easy to build, you need 16 green connectors, 8 pills (green rods), 1 white rod, one purple connector, two rubber bands,two blue connectors, connected, and last but not least a blue rod. Heres how to make it. Follow the pics.
Step 1: Things You Need
Here's the stuff you need.
Step 2: The Pin
Here's how to make the pin. Follow the pics carefully to see how to do the rubber bands.
Step 3: The Body
Here's the body. Make sure it doesn't fall apart in your hand.
Step 4: Put It All Together
Now you just have to put it together! Then you can blow something up with your new grenade!
Step 5: You're Done!
Hope you have fun with my new KNEX grenade!
