Based on how fast they bug out when a seal bomb hits the water, I suspect it's more than just a little ear ringing. I suppose it all depends on how far away the bomb is when it goes off.

"A single accidental human death has also been recorded and retrospectively studied; a swimmer was killed when a bomb—containing 3.0g of explosive charge—exploded within 0.3 meters of his body. The explosion “ruptured both eardrums, herniated brain tissue through ruptured areas in the cribriform plates, fractured cranial bones including the wings of the sphenoid and the left petrosal, and caused a 1.5-cm-deep wound above the scapula”

if headline read 'bomb' instead of explosive I'd agree with you, but explosive seems about right. What term would you suggest considering few people have ever heard of a bear banger

An m-80 has about 3 grams of powder. These seem nowhere near that powerful

Firecracker.

How does Danny Hart sit down with balls that big?

The googlatrix told me that it’s considerwd a firearm in Canada. Searched before I posted. Of course I took the first website I read as gospel so take that for what it’s worth.

Eh, I'm no expert but they're not far off of an M-80 in my limited experience.

Quick search results:
"(c) "Seal bomb" means underwater firecrackers available domestically, similar to "M-80" firecrackers and contain approximately 2.3 grams of "flash and sound" charge mixture in a sealed cardboard tube, fitted with an eight to nine second waterproof fuse. UN0471 Class 1.4E explosives or NA0412 Class 1.4E explosive."

"The seal bombs used in this study had a charge weight of 2.33 g flash powder using a standard formulation of about 64.0% potassium perchlorate (KClO4) as the oxidizer and a fuel of 25% aluminum powder and 10% sulfur (personal communications M. Stonebraker, Stoneco Energetics Systems). This charge weight is similar to common M-80 salutes."

This whole post just makes Canada look bad. Either you live in an ass backwards place that considers a toy something you yell "Wolverines with" or you lack Google Fu

There are two main reasons explosions under water are so deadly. The first is that water is basically incomprehensible, so energy of the explosion compresses your body much more efficiently than one in air, since it doesn't waste energy compressing air. The second is how waves react to changes in density. An explosion in air will be reflected when it encounters something of higher density (like most of your body), but will compress some of the less dense gas filled parts of your body. A blast wave moving through water is the same, but will only be reflected well by something denser than water, so the wave will move through much more of your body and compress the gas filled chambers even more.

Even a small explosion under water is very dangerous.

Sea Lion was just politely asking questions.

I safer way to experience the water hammer effect used in blasting is to clack 2 large rocks together underwater. You get an idea of how the "compression" waves travel. The wave is just higher velocity particles.

And thought I understood water pretty well.

Chappy is full of useless knowledge.

Perhaps, but the issue isn't the quality of the information (he or she is right), it's the use of the bolded word, which is not a property of water.

I meant incompressible, but auto correct. In fairness, the behavior of water is hard to comprehend, it does all sorts of weird things. Just look at this thread and the people that don't understand the danger of explosions in water.

maybe that's why they said "sparks" instead of some word for a bigger fire ;-)

If you're injured and need some sympathy, PM me and I'm very happy to write back.

Figured it might be an autocorrect kinda thing 'cause you were spot on in your assessment. And you're right - water has an astounding range of properties.

Do you know if that works for bottlenose dolphins that are trying to steal red snapper off of your line? Asking for a friend.

Yeah. I don’t understand water either.

I dunno. Cetaceans are pretty smart. Your situation reminds me of this:
