Someone told me there were some ways you could get the soft rubber swords that drift, bludgeon, etc have to become solid. Someone mentioned something about hot water. Can anyone help me with how to get the swords to become solid?
I think you misinterpreted it. People fix bend soft plastics by merging them in hot water (which will soften it) and run them thru cold water (which hardens it) while maintaining the desired shape.
I don't know what changed in 25 years, when I was a kid our optimus primes had hard pointy smokestacks, and I wasn't ramming them into my eyes.
