Just as a side note I have a BS in chemistry and other topics, just so that I could understand fireworks and explosives, in greater detail.
In HEX there is a pressure gradient,as gas expansion occurs, not flame expansion. The best way to delineate between HEX and LEX is that HEX exhibits the Munroe Effect... which I leave that one for Ms Google
One item at the borderline between the two is flash powder. In the US it's considered a HEX 1.1G for storage purposes. Flash does not need to be confined tightly to explode. And an explosion involving flash looks like a detonation
I don't know if flash exhibits the Munroe Effect though

"The Torpex filling was poured into the base of the upturned casing by hand, after melting it in "kettles". The final stage of explosive filling required that a one-inch layer of pure TNT be poured over the Torpex filling, followed by sealing the base with a 4-inch (100 mm) layer of woodmeal-wax composite with three cylindrical recesses fitted with the explosive boosters and into which (when the bomb was finally armed), a total of three chemical time-fuses were inserted."

No bloody intention of trying it!
My chemistry master at school had lost an eye earlier in his career when an experiment was rather more spectacular than planned, put me off making things go bang for life.

As others have said good way of dredging canal and getting some fish as well. The Gulls were certainly in quickly. I wonder how they found it after all this time ?

I've been making things go bang since I was 15... especially my beloved fireworks... I've synthesized TNT, Trintro aniline ( tetryl) Ethylene glycol dinitrate, And trinitrophenol (picric acid) don't ask me where I got the chemicals and the apparatus. and how did I get blasting caps Lol
and the heavy cruiser Prinz Eugen. Eighteen Lancasters of 617 took part with fourteen carrying Tallboys. Escort was 127 fighters but the opposition was solely flak.
One Tallboy exploded between the Lutzow and the side of the canal smashing in her arrmour plating below the waterline and she gradually settled by the stern. As this was in shallow water her guns remained in action until the Russians occupied the port when she was blown up. The Prinz Eugen survived the raid.
Most of 617's aircraft suffered flak damage and one was lost over the target. Sadly no survivors. Apparently the RAF film unit's mosquito accompanied the raid so there maybe something on you tube.

According to an article I read the other day it was found NOSE UP in the mud. Had it been 180 degrees about the effect would have been much greater!

I think that wartime raid film shows this Tallboy making a splash in water, as there is a splash that is a lot smaller than the other Tallboys that clearly explode, and its a big enough splash to be a 12000lb Tallboy hitting the water and not going off.....and if you freeze frame both films and screen shot it, it does look very close to being the same one.....but I'm not an expert.
The ship would have been in front of the saw tooth dock structure that has been built since, but the jetty coming down from the two U-Boat pens on the opposite site appears to be roughly the same still.
