Going off on a bit of a tangent here, but how about testing the sounds of passing bullets? I've been re-watching Band of Brothers this past week and have been wondering about some of the bullet sounds in that series.
During training for my tour in Iraq back in 07/08 we had to sit in a fox hole at a firing range and listen to the sounds of bullets being fired above our heads, to allow us to distinguish the difference between friendly and enemy rounds. STANAG 7.62mm and 5.56mm and the 7.62x39mm (AK47) rounds don't sound anything like what you hear in Band of Brothers. But then again, that's not what they mostly used back then. For the standard German infantry rifle, the kar 98, it was the 7.92x57mm Mauser round, commonly known to Americans as the 8mm Mauser round. MG42's did use something very close to STANAG 7.62x51mm in size, but I'm not sure what they were jacketed with back then and if that even makes a difference.
So, how accurate are the sounds used in Band of Brothers, a series that was and is widely heralded for its historical accuracy?

I'm sure they would have to put microphones downrange instead of hunkering in a foxhole, but with speakers in their safety bunker, we could still get reaction shots.

Watching something from Hawaii 5-0......
Trapped in a collapsed building, Steve and Danno need to shift some debris, Steve takes a small grenade from his belt, and dissembles. Danno meanwhile has found a piece of water pipe, maybe 6 inch long, and flattened one end to close it off. The powder goes in the top, I think from the initial detonator, 'cos I dont think they use Powder in the actual charge these days do they?... Anyway, he then goes and puts the internal cotton wadding from a petrol lighter into the end of the pipe, and lights that.....
For starters, this "Powder", I thought that was a chemical reaction in the initial detonator?... it lights with a petrol lighter?.... Second, I never seen him smoke, where does the lighter come from?.... Third, thats enough powder to shift concrete?... from a crude pipe bomb from 16mil water pipe?....

Sort of New... They driving about in this... So yes, New, but last season... well, last season here in UK..... The sort of blast they got was "Heard" 30ft through rubble from an underground car park that had had a building dropped on it. We didnt "See" the blast.

Not an explosion per se, but would the guys be interested in another PSA-myth on handling ammo safely? A kid at a local school just got in the news after he swapped some Pokemon cards for a 22 caliber bullet at school. (The story's here, if anyone's interested in reading it.) A reporter interviewed a couple employees at a local sporting goods store, and this bit jumped out at me: (There's another reference to setting off a round with a lit match, but that might be too close to the "Hot Bullets" episode.) Just how sensitive is the detonator on what I assume is a .22 rimfire? Can you really set one off by running over it with the vacuum, or was the interviewee's friend perhaps using reloaded ammo that wasn't quite up to spec?

well, reloaded rimfire ammo would have to have a new shell - making it a factory load for purposes of accidental discharge. (I've also never heard of reloading rimfire ammo for that reason. reloading centerfire ammo is accomplished by replacing a factory loaded primer, but reusing the brass shell casing or shotshell hull.)
when I was a kid, a friend and I swiped a couple of primers from his father's shotshell reloading press, and set them off by crushing them with rocks - but we had to hit them pretty hard to do it. on the other hand, it takes very little pressure to compress the spring for the firing pin in a .22 rimfire pistol or rifle. I would expect it to require a vacuum where the impeller was in the suction path to have anything that would actually crimp the rim in such a way as to trigger the primer material, though.
still I think it would be testable - they already made a remote vacuum rig - and they could start by vacuuming spent shells with plugs glued into the ends to make them the right shape to simulate unfired shells - and see whether they developed any extra crimps on the rim.

As a side note, you've gotta love the dad's reaction! We give a lot of parents flack on this forum for wanting everyone else to parent their kids. Here's a guy who gets it. He doesn't blame gun manufacturers or US laws or anything like that. He just goes, "Parents should be more responsible" and praises his own kid for doing the right thing by telling him what happened. Kudos to him for being a better dad than most who are mentioned on this forum.

Back to having a blast. get a sealed chamber with a mix of 14:1 air and fuel with a drive in powering a wooden dowel spinning on another piece of wood, the kind of wood built drill used to start fires.... I use that illustration here so we all know what I am thinking?... Well it could be powered by a drive to an electric motor outside the "box", for box, think am I missing an eyebrow type experiment..... ya think that could create a good ignition source?... Could it be controlled..... I am cross threading an idea for wooden engines. citadelofmyths.freeforums.net/thread/200/wooden-car?page=8&scrollTo=53454

This sounds like a myth but it was in the AP today: "Police spokeswoman Petra Datscher said Monday a World War II grenade apparently landed on a tree during fighting. It was then enveloped by wood growing around it to the point that it was invisible when the tree was chopped down for firewood and sold to the supermarket where the unidentified 22-year-old woman bought it." It went off after she lit the fire. hosted.ap.org/dynamic/stories/E/EU_ODD_AUSTRIA_FIREWOOD_EXPLODES?SITE=AP&SECTION=HOME&TEMPLATE=DEFAULT&CTIME=2014-12-01-13-23-56Several myths: 1. Would a tree grow that fast? 2. Would a grenade last that long? 3. Would it be invisible? 4. Would a stove survive the blast?

It would depend on the species of tree I guess, but near me there is a fence line with some oak trees growing near it, the oak tree has now grow in such a way that the wooden fence rails have become enveloped by the fabric of the tree. Edit,,this blog has picture of something similar . scienceblogs.com/gregladen/2013/01/29/whispers-from-the-ghosting-trees/

Would a tree grow that fast? 2. Would a grenade last that long? 3. Would it be invisible? 4. Would a stove survive the blast? 1,2,3, yes. 4, no..... In UK and europe we still find live unexploded ww2 ordinance now and again. The general consensus is expect it to be live until proven otherwise.. Do NOT try to prove that yourself. If its a soft-wood tree, then yes, it will grow fast.. I have over 100ft trees behind my house that were planted in the 50's. they are not softwood. one of them is an Oak.... that one may be older.... I also have softwood Pine that is growing in my back garden that is already taller than the house... its 10 yrs old. If ordinance is grown over by the tree, and encased, it will be protected from the weather, so may be extremely live. Its also "Contained".... If explosives are contained, they build up pressure, so a grenade encased in wood, I have the suspicion it would be a stronger blast?... Proposal, if Jamie (Who wants a bigger boom) could get a tree trunk piece and saw in half, make a hole, and put in a live grenade... you will need two the same...I suspect the local bomb disposal team will be involved there, make it a tight fit, pack it in with sawdust or whatever?... seal the two halves together with wood glue, just so the join is stronger than surrounding wood. You will have pre-drilled a small hole so a wire can be used to detonate the device. Now go to the range. Explode the second grenade with no restrictions. Now try the one in the wooden overcoat..... Expectations, it will be a bigger boom.

I wonder if it was possible that the main charge had degraded but the primer or detonating charge was intact. Could be enough to rattle the stove and break the glass without destroying the stove.

I suppose define "Stove" as well... I have known a few ranges that could be almost explosion proof?... You know the ones... "Your only supposed to blow the bloody doors off".
