I think the brick was better but its still cool

This sort of thing is really cool from an eco standpoint. Could really easily build a shelter out of those.

You either want a club, or a stabbing/slashing weapon when you grab a bottle. Breaking a bottle over the head is cinematic, you’ll get some blunt trauma and likely some lacerations. But the shattering of the bottle dispersed some of the force. You also generally would want to break a bottle before you hit a person with it if your intent is to stab or slash- this give you the best chance to get a good break and avoiding cutting YOURSELF when the bottle breaks. Way back when- some bottles were very sturdy. Galliano was a decent bottle not prone to breaking, and of broken could be used effectively. Having not had my hands on one of these cubes- I can’t say. By the looks of it- it might make an effective throwing weapon. I wouldn’t try to break this one I don’t think... and I don’t know that I’d want to use it as a club. It seems like your risk of self injury could be high. But thrown right and well/ this one maybe could be an effective weapon.
