Do you have a weapon that can burst a bag of water

Sure you have.
Even your Bee-Stinger guns can do that.

But do you have a one that can shoot a hole without losing a drop of water.

Demonstration of an out dated projectile:
Notice the mass water loss

No water spills out the holes because ziploc bags are made of a polymer. Polymers have long chains of molecules that are flexible. When you poke a sharp pencil through the baggie, the pencil slides in between the chain of molecules that make up the polymer. The molecule chains make a seal around the pencil that won't let the water out.
