K'nex Grenade With Pin

This is a good k'nex grenade, there is a low piece count, the pin stops it from exploding all the time, and it makes a nice explosion.

The idea is simple so sorry if this has already been made.

Please comment.

EDIT: I have made a better grenade at https://www.instructables.com/id/Knex-War-Granede/

The pieces are:

2 white circle connecters

Step 2: TOP

Wedge 8 of the red corner connecters into on of the white circle connector.

Step 5: ATTACH TOP, SIDES, AND BOTTOM
