Go to Post So why are we trying to go to Mars? It's because it's bigger, better, and bolder. Doing what nearly no other team can do, and defying all those who say it can't be done. That reward is a lot more than 9 points. - Mike [more]

that doesn't prove if marbles will break on impact but if i were the judges, i might say that it is a hazard in the field because IF it breaks, it can be sharp.
i'd check with FIRST if i were you.
i'm also looking for a way to help us turn easier. i'm not sure zip ties are the best way either. if anyone thinks up an idea, please contact us or post it somewhere.thanks!
ANother idea is to buy flooring epoxy (have you ever seen an epoxy floor -- I have one in my house, its good stuff) and cover the kit pneumatic wheels with it and let them harden. Then you have (basically) wheels with epoxy treads, plenty slick enough for you.
