This is a rip off of the splodie, which uses four pieces and has better range.

This is no where near that splodie design an it fires heaps good.

Well if you can't really fire it it has some major flaws, such as, not being able to fire...not really understading how to fire it...not being able to fire. But really, some knex things work great and some downright suck. Yours is leaning towards the latter.Matter closed.

How To Fire: First you put the end of the grey rod on the ground, then pull yellow connector/white rod object down, and... RELEASE!
