Yeh, it ain't safe for idiots

It isn't safe for anyone. The reaction goes faster if the chlorine is finer.

Yep - too unpredictable / too many variables.
The advertised purity and concentration of chlorine [even when new] is dubious, as is brake fluid - often the stuff that the "soon to be an inpatient" is using, was nicked from their Dads shed.
Lord knows how old / what grade / chemical composition / how much water it has absorbed.

When tested under proper controlled conditions in a proper segregated testing area for this sort of stuff, we found that ignition times varied from virtually instantaneous to several days later.

In all honesty - you really need to know exactly what you are doing in this game - don't risk it!!

yes, from memory I think 30% water gives the best result, added bonus is you can set up somebody to get a drenching when it takes off.

I was always the mug getting drenched.......

nebbian said.. Come on, we all know SN has access and skills with... um... stuff that scares normal people

Yeah, I remember watching a program on forming steel panels by placing them in a pool next to some sort of mold or former, and then exploding something in the pool... I think this is the sort of thing that SN might be good at, but I am not sure the pool would survive.

did this in a farm dam - to use the hydraulic shock wave to seal a leak in the dam.

sealed the leak - but emptied the dam of around 80 years worth of incredibly smelly silt, old wire, bits of machinery and what I presume was most of a decomposed sheep, along with 675653467897907 coonacs.

handy tip for beginners - never park your ute downwind of a dam that is being depth-charged

Well - it was an eventful day...

Two of the minions and myself made a volcano in the corner of the backyard, with a special mix of stuff in the crater which produced a very nice pillar of fire and smoke.... just in time for the Ministry of Supply to walk around the corner to see the boys champing at the bit waiting for my ok to put out the volcano.

Their Nana got a bit flustered, and between the usual "WTF YOU ARE SUPPOSED TO BE SUPERVISING THE BOYS" [in a rather panicky tone] and her trying to get her phone out so as to compile more evidence for the coroners court - she fluffed it and missed out.

Which gave us the perfect reason [excuse] to set up "take two", using the dregs of the mix [about 40 grams] and sacrifice yet another CO2 extinguisher in the name of science

no children were harmed in the course of this "educational experiment", but the sacrificial dinosaurs are now molten blobs - and I think I might give the olives a miss this season

3 x CO2, 1 X 9L water, and 1 x dry powder extinguisher heading for the scrappies next week....

I think it might be a prudent idea to postpone the exploding nerf targets until next visit

Ha! I think the grandkids will be loving that!

Your neighbours probably love you the same way mine did when I was playing with rocket stoves. Until they get burning there is a lot of smoke, and no one ever feels comfortable watching smoke drift over the fence from the neighbours house.

Don't chuck the empties. You'll need those for the flame throwers.
