Okay, so I've been seriously thinking about this for about 30 minutes. A homemade water bomb. Okay, now here me out. Potassium metal reacts with water and makes it go boom. You can easily buy it though it is pricey. Now if you coat that in Polyvinyl alcohol the same material used for laundry pods and get enough of it into a water system the coating will allow you enough time to get away before it goes boom. Would this theoretically work?
