From the article:
"Ballistic gel is a broad term referring to a large chunk of dense gel generally used in firearms-related testing to reliably and consistently measure things like bullet deformation, fragmentation, and impact. It’s tough, elastic, and in many ways resembles a gigantic gummi bear."
Yeah, but ballistic gel tastes awful.

It only happens in the oil based clear gel. If you use the organic gel, it won't do that.
Also, an FYI, penetration is clear gel is approx. 20% further than organic ballistic gel, because the oil based gel is slicker....Slow motion video capture is a natural companion to just about anything that you’d need ballistic gel for, and good thing — because the video captured what appears to be a diesel effect! The block is hit with a bullet, and as the bullet rapidly expands and dumps its energy into the gel, a cavity expands rapidly. During this process, some of the (oil-based) material in the cavity has been vaporized. After the expanded bullet exits (to the right of the gif above but easier to see in the video below), the cavity in the block begins to collapse. The resulting pressure increase appears to ignite the vaporized material, which explodes with a flash followed by some exhaust.
Here is a double explosion on a Jerry Miculek video at about the 4:20 mark:
I have to admit, the .460 Magnum would be kind of cool to own. I know a fellow in Iowa who hunts with one. He said he's bagged whitetails at 200 yards, easy.
P.S. Hmm, I wonder if these little mini explosions could actually be happening in soft targets like humans and meat animals and the effects it could have? Especially on the nervous system if it hits in the right spot. It makes me wonder about some of the subtle differences between terminal effects of hydrostatic shock and hydraulic action of meplat wounding characteristics at higher speeds (say above 1,000'ish fps?).
At least my observations on tasty animals I've shot and have seen others shoot with big flat point bullets. The permanent wound track tends to be larger than the caliber, and something like a 357 or 44 Keith style bullet going 1300-1400 fps seems to pack way more punch than it should. Not always, but often enough there is something there. I've seen too many bang-flops from "underpowered" straight wall handgun cartridges. As I recall Col. Doug Wesson used his 8" S&W shooting a 158gr SWC at about 1500fps and down an awful lot of big game with it at distances most would scoff at using a handgun. And he wasn't emptying an entire cylinder either. I believe most of them were 1-2 shot affairs.
It makes me ponder too all those "one-shot stops" from the 125gr 357 Magnum semi-jacketed hollow point doing about 1400-1500fps.
I once worked with a Crime Lab guy that spent a lot of time trying to replicate this. About the time he was ready to say it was a myth , He finally caught one. He also spent a lot of time on handgun Hydrostatic Shock. If you liked bullets and what they would or wouldn't do, He was the guy to know! DR

Gotta burp them blocks beforehand, so they won't be so gassy !!!
