For this creation, you simply need 9 white pieces, and 6 rubber bands
Step 2: Putting it all together
Now for building the grenade. Slide the white pieces into each other as shown, then continue to inster the pieces untill you've connected all the pieces
Step 3: Making the fakeness
Time to make it a fake grenade. Take the rubber bands and wrap them around the entire body. WARNING: The white pieces often fall off, causing much frustration, don't give up though! Put on the first rubber band like shown below.
Step 4: Additions
Then, continue to add the rubber bands, one band per slot. When you complete one side, fill the other.
Step 5: AAAAAAAHHHHHH!!!!!!!! Wait, what the...?
Now you've completed the fake grenade. Sometimes when you drop it, it will crumple together, but most of the times, it'll just fake out your victim.
