American kids can no shoot their school mates in the pool too
Great, more ways to murder each others
Were the previous ones drowning?
Im not sure I fully understand the event that just transpired , cap???
So generally speaking (steam-) cavitation happens when static pressure in a fluid falls below the evaporation-pressure thus making the fluid evaporate, building bubbles in the fluid. There is also gas-cavitation where solved gases in the fluid "come loose". It's a effect you generally want to prevent from happening at (moving) parts in fluids as the implosion of the bubbles can damage said parts substantially in the long run. Seems like those bullets provoke cavitation on purpose, I'm guessing by either shape, velocity or rotation, to create a bubble with either steam and/or gas (see above) that starts at the tip of the bullet. It prevents or minimizes the bullet from having contact to the water, thus greatly increase the distance it can travel in water. They say on their website the bullet also can harm without direct hit - I guess that's the cavitation bubble bursting with high velocity. Actually that's, fluid dynamical speaking, a fucking creative idea!
Schools of fish better watch out
The question would be how these perform outside of water. If the ballistics are crap, no one will bother using them.
