Here's a 1921 Pop. Mechanics method of clearing a drain. Sounds quite exciting!

Drain clearing

[Mick B1Participant @mickb1]

Don't do this at home, kids…

[duncan webster 1Participant @duncanwebster1]

Reminds me of many years ago when I was trying unsuccessfully to run an EDB diesel. Fuel was home made equal parts of diesel, redex and ether. My Dad decided to get the pot bellied stove in the kitchen going by dousing the coke in ether and applying a match. Not only blew the doors off the stove, all the coke was spread around the kitchen together with a lot of the soot out of the chimney. Mother was not a happy bunny. Neither was I as he didn't volunteer to buy more ether. Strange how as a teenager I could just wander into Boots in a small market town and buy such stuff no problem.

A ‘P’can (or thereabouts) of TVO, splashed into the smouldering embers of the boiler fire, then standing back and waiting for the ignition was the usual trick to get the fire blazing again. Throwing it on, just before someone entered tthe room, could give them a bit of a surprise at times! We never stood in front of the fire unless it was flaming well – just in case….

We were told at school or Uni I forget when that aluminium smelters had a habit of blocking their air holes with slag so after WW2 the surplus of bazooka shells was used for unblocking them.

[HacksawParticipant @hacksaw]

Great for collapsing mole tunnels too !

Wasn't there was a " water pump" that worked by igniting a gas in a u bend , or a chamber , with a clack valve on the outlet end to stop the "pumped "water returning under gravity ….or something like that ??

Might have read an article it in ME or Stationary Engine ..

[John MCParticipant @johnmc39344]

The water pump is the "Humphrey" pump. I visited an installation in Chingford (UK) many years ago, not working but still in place. I wonder if they are still there?

Sawdust sweepings from the joinery shop floor would be cast into the iron stove, the lid jammed on quick and a concrete block hastily placed on top.
The resulting crown fire would procede along the ducting and shoot forth singeing the hapless joiners who had carefully directed the hot air vents toward their work stations.

In an older ME there was a bit about how you could, before WW2 buy a little packet of gun powder, that could be put in the close fire box of the copper in the laundry to blow out the soot from the chimney, it also mentioned the effect of putting in 2 packets.

As kids we made bombs from the heads of Wax Vesta matches.

My Dad used to tell the story of his Dad removing soot with a charge of gunpowder – did a lot of damage to the chimney breast dislodging many bricks!

An ex-Crewe Works old boy related to us students how they got fed up with one fitter who was always nicking coal from the works to take home for his domestic fireplace. One day at the end of the shift they put a detonator in his coal sack. Apparently the resultant shock and mess stopped his further theft of LMS coal.

Still going! Google 'stovax' I think it has an excess of oxidser in it.

There was also 'imp' which was a little volcano shaped 'firework' you put in the grate as I recall.

A rather less exciting country remedy for soot clearance in chimneys was to suspend a hapless chicken on a weighted rope and lower the poor creature down the chimney. It did pay to block the fireplace properly before doing this

The alternative, but much messier way, was to let fly with both barrels of a shotgun shoved in from the bottom!

A fellow around the corner here in Canada got a new house a few years ago after cleaning up something with gasoline (petrol) in his basement.

Lots of us have natural gas powered domestic water heaters – big vertical cylinders with a pilot flame on the bottom.

Needless to say, pouring gasoline down the drain, having the fumes waft up and around the water heater was a recipe for disaster.

All survived; house rebuilt; not a trick I'd have chosen to get redecorating done!

When we were kids (young teenagers) we used to make a basic 3 ingredient black powder, the fun we had with that. How none of us suffered serious injury I dont know, I could also tell you how to make a simple marble gun but they are seriously dangerous so I had better not….

[SillyOldDufferModerator @sillyoldduffer]

Big problem with many of these old time wheezes is the results are unpredictable. It's rather difficult to get petrol vapour to explode at all and there's also a chance of it going bang with exceptional violence.

• If the petrol-air mixture fails to ignite, you've doubled your problem – now you have a blocked sewer contaminated with petrol.
• If the mixture goes bang and the blockage is firmly stuck the force of the explosion will be applied excessively to the structure and it will vent at any weak points. (Having a cast-iron man-hole cover fall on your head would ruin your day.)
• If the mixture is optimum and multiple reflections of the shock wave bounce off the walls and lots of internal debris, the explosion will be unusually rapid and cause massive damage.

As a way of unblocking a sewer I wouldn't touch it with a barge-pole!

But the chemists often sold you 'Chile' saltpetre (sodium nitrate – and hygroscopic) instead of the real thing. OTOH, in those days bonfire night tuppenny bangers 'Little Demon' and the aptly-named 'Cannon' contained quite a good, glossy black powder that I'd now guess roughly matched FFG.

I was lucky to get away without permanent damage to my hand when I tried to make a 'recoilless' cannon using this stuff and other ingredients.

For all the stories you hear of a lucky success, there are at least as many of serious consequences, which you don't hear told so enthusiastically.

[Chris TriceParticipant @christrice43267]

A friend of mine blew up his vacuum cleaner sucking up rust residue at the bottom of his petrol tank. Obviously a spark in the vacuum cleaner motor and the fuel/air mixture was just right. He remembers lying on his back six feet from where he had been with the shredded remains of the vacuum spread liberally around him.

"both barrels of a shotgun shoved in from the bottom!"

Would that be the bottom of the chimney or the bottom of the chi…………….? I agree, it does sound messy.

[SamsarandaParticipant @samsaranda]

Whilst still at school, myself and two friends experimented with a number of home made explosives,( grammar school chemistry curriculum was great for expanding our knowledge, in the wrong direction). We used to use pressure to detonate our mixtures, this was achieved by making small parcels of mixture which was then placed on the rails of a local rail line and waiting for a passing train to detonate it. Some mixtures were more potent than others. In those days we believed we were immortal and no harm would befall us, how lucky we were not get injured or worse.

Years ago, young fellow tried to light a pot bellied stove by filling with paper, wood and coke and soaking with cellulose thinners. Resulting explosion demolished stove and removed most of his clothes. Daveb

As a child of the 50’s we had fun

 

1) dad was  A radio engineer with lots of aluminium tube. With 2 pence rockets these made great bazookers one aimed, one lit the rocket. Still got me eyes i don’t know how

2) we loved throwing bangers, light. Count. To 4 throw. And use as a grenade. Problem was when the new banger 321zero was introduced it went off in three seconds of fizzing. Still got me hands  amazing that a kid under 10 went n spent all his pocket money at the corner shop on gpbangers, rockets and jumping jacks

3). Penny boxes of caps go off with a tremendous bang if you hit the closed box with a big hammer. It jumps high and it makes your ears ring….. perhaps this is whi I have tinatus now….

4 home made gunpowder was fun

5 cross bows made with 3 layers of 4 mm square elastic with a green garden cane as a bolt, weighted tooth Dad’s solder were deadly accurate. We gave up that game after one of us got hit on the forehead his dustbin lid shield was down. He still has the scar.

How did I survive? Kids in this elf n safte days don’t have much fun……. but I’m getting an Arduino for Christmas …..
