This a fun thing to do when you are bored, have a lot of Knex, but no rubber bands. this shows how to make a fun knex "battle car". me and my friends used to do this all the time. make two "battle cars" and crash them into eachother from accross the room, the first one to lose all thier wheels loses.
this is a very simple version of the battle car, and there is a million ways to customize it, i hope to see a bunch of different versions pretty soon.
It works best on flat sufaces (aka, concrete, hardwood floor, ect.)
oh and this is my first instructable, so critisize all you want, but be constructive, no "this sucks" unless you have a fortified reason.
