To block out all sound, we'd like you to think that buildings would need walls several metres thick. Now Yang and his team have developed soundproof(ish) panels made of latex and plastic buttons, that we'd also like you to think will do the job (Applied Physics Letters, DOI: 10.1063/1.3299007).
These noise-cancelling panels consist of a latex rubber membrane stretched over a 3-millimetre-thick rigid plastic grid of 1-centimetre-wide squares. ... (as though that made a heap of difference to you. Just buy these, OK? You won't regret it. )
Just thought I'd do a bit of technical editing.

Its also funnier that way if your trained idiots like us and went to the silly school of phsyics
