Now I'd like to call your attention to an invention that has gained Elena Bodnar the Ig Nobel prize in public health. Elena invented a bra that can be turned into a pair of face masks. According to the patent, each cup has a filter device so the wearer can protect herself while also offering a mask to a lucky bystander. In the case of a serious emergency, I suppose women won't mind ripping of their shirts and sharing their bras with someone else!
