I’m trying to work out how to model the destruction of the towers using glizzies. What would I have to build the towers out of if I wanted to throw hotdogs at them to destroy them?
Cardboard is obviously too strong. Wax paper has too much tensile strength but crumples satisfactorily. Does anyone have ideas on what I should use as the tower materials?


0.67 percent the speed of light would be enough. That’s mach 5800, or 2000 km/s. A 50g hot dog would have around 10^11 J kinetic energy.
If you accelerated a 50g hot dog to 10 percent light speed you’d probably have enough energy there to destroy civilization.
