Dude i had to wrap my bands around twice, and when i tested the pin, it actually crushed in the middle a bit, so it was bent inward. however, when i reinserted the pin, it went back to normal. VERY POWERFUL WEAPON!

 I looked at the knex website and apparently you can order knex parts individually. If I were to buy the parts for this grenade, it would cost me a grand total of $5.48 US currency. That's kinda expensive.
 yup, which is why you ALWAYS buy in bulk

 built it, it completely rocks! I give it 9/10, -1 because sometimes it can be annoying to put together.  But it definitely works, doesn't use up too many pieces, and can be made in less then 5 minutes.  :D

im building a jurrasic park knex rollercoaster!
Favourite movie
lost worlds my favorite(the way us americans spell what you guys spell as favourite)
cool, will the roller coaster have like a track like the movie, or will it be a dinosaur themed mayham park
well... i kinda let my second motor to power the t-rex into my sisters view. shes five, but shes wrecked lego models, knex stuff, and a nerf gun(at least dad got me another recon).wouldnt be a whole lot of fun to watch without it. its still in the design phase, too. oh, are you going to see the fourth one thats comin out soon???
you bet! It won't be very good though, what I liked about the first one was how there was the guy who hates kids with the two kids, andhis girlfriend was trying to save them, but they wrecked it in number 3, with his girlfriend marrying someone else.
