The Knife That Turns on a Shark: Survival Tech?

Описание: Stab the shark and press the button on the knife’s handle.
That action activates a hidden CO₂ canister inside.
Immediately, the canister explodes and forces a blast of freezing compressed gas through a tube built into the blade, spraying out the tip.
The cold gas is injected directly into the wound, where it expands rapidly and violently, destroying surrounding tissue with tremendous pressure.
The shockwave is powerful enough to make the shark burst from the inside, killing it before it can kill you.
