    K'nex grenades that don't use tension don't have a blast radius, elastic band ones are a lot better.

    well, if you get like three wheels, and do that thing where you connect them with green rods, and throw it, you get a great knex grenade

    actually true but you don't have to have tension to have a blast radius you just throw it hard but i tried it with rubber bands and it did work a lot better if you wont to use elastics just put them over the two orange connectors

    It would only implode with the current design, unless you found an original way of attaching the elastics.
