I made two knex grenades both of them explode and have pins you must pull before you through tell me if i should post the second one. It not only explodes but is also filled with shrapnel.
If you have any questions just ask, either on my orange board or in the comments.
**this one i will show you how to build is built mainly for looks but also functions pretty well I have not seen this type of grenade that actually explodes yet, if I am wrong please correct me.**
Step 1: Parts List
Sorry its a little blury but youu shoulde able to figure it out.
Step 2: Buliding
I'll do this all in one step considering it is very strait forward; feel free to ask any questions you may have.
Step 3: Done....How to Use.
To use it just stick your finger in the finger pull/ring and pull. If it comes apart and the semi circle piece doesn't come off, you can either put some tape around the Y connecters or lift up a little on the ring before you pull. After you pull off the top holditupright and the pin should just fall out, now go have fun!!
