Introduction: K'nex - Mystery Box

Hey guys, now instead of doing my usual routine where I use pictures of K'nex guns from other Instructables members to build my own versions of theirs and then write a review on it but I have done something completely different.

Because I do enjoy playing Call Of Duty: Zombies alot, I got the idea to build this when youtuber ZaziNombies made his own Mystery Box out of over 10,000 lego pieces and it thought to myself that I could make one out of K'nex and I knew the dimensions for one.

Anyway let's talk about the Mystery Box, basically it appears in every single zombies map and what it does is, it gives you a random weapon for 950 points. After the Mystery Box has been used several times a teddy bear appears and it moves the box to a different location in the map and you get your money refunded as well. If you pick up a Fire Sale power up, the box will spawn at every possible location and the price is reduce just to 10 points but this will only last for 30 seconds.
