Scientists at ETH Zurich are developing a groundbreaking gel that could prevent hangovers before they start. This innovation aims to mitigate the unpleasant effects felt after a night of drinking, such as fatigue and nausea. The video showcases the science behind this potential solution, highlighting how materials scientists are working to improve our mornings and redefine responsible drinking. If successful, this could mark the end of hangovers as we know them.
