One day I was building K'nex grenades and the one thing that I noticed was that none of them really exploded. They just kind of fell apart, so I decided to develop my own. I spent hours trying to find a way to actually get the pieces to fly off. Finally I hit upon this design. It explodes so well that I am still looking for pieces that had gotten lost during testing.

The blast radius is about 10 feet, so do not throw near people, animals, or breakables.

Have fun with it and please rate, comment, and subscribe!

I like it! 4*
WOA. This is a pretty smart design! i never would have thought of that :) I threw it and now i cant find 3 of the 90 degree angle pieces, lol, ill probobly find them, in a year or two. i threw it in the center of my room in pieces litereally hit the walls and slid down behind my bed and dresser.

/!\ WARNING /!\
Be careful when you are putting the Red pieces (or in my case, grey) onto the white pieces (or in my case black) I one flew off and hit me in the nose! :P

i give this 4/5*s. (you would get the last star if you had some clever way to find the pieces again! haha)
