This post doesn't provide any emergency-related context, so it's more of a physics question than an emergency preparedness question, and we see you've already asked the same question on r/AskPhysics.

If you don't get a satisfactory answer there in the next couple of days, and if you can reframe this as a practical emergency preparedness question, then you might submit your reframed question here and we'll review it again for possible approval. However, please don't do that while you still have it as a pending question on r/AskPhysics.
