what would really be cool is 50%+ h2o2 igniting hay bales, i wish i could do it but im honestly scared shitless of h2o2 of the concentration

I saw the link from the video page to the Make article - congratulations! That's really great. I'm happy that the article writer mentioned one of my
submissions as a favorite  Very exciting! Our fame is spreading!
By the way, once a Part 2 gets rolling, I recommend we start a new thread for it since this one's up to 15 pages now.
edit: make that 16!

H2O2 that concentration really is frightening.
While I agree another thread is better for ease sake, I would want the input of a moderator. I know excessive threads are looked down upon and I see
thread merged all the time, but those are usually small, so I'm not sure.
To review, here's what we have lined up for part two so far:
KMnO4 and brake fluid
KMnO4 and DMSO
NaDCC and DMSO
Turpentine dumped into RFNA and KMnO4
(these 4 thanks to Formatik!)
Pyrophoric iron (possibly)
Phyrophoric Iron dropped onto ethanol (or other flammable liquids. In progress)
(Thanks to TheNaKLaB for those).

This weekend I'll try and make aluminum boride from aluminum powder and boric oxide, in turn to make self-igniting borane. Any suggestions for how I
should do this? Right now I'm thinking:
1. Mixture of 3-4 mol.eq Al and 1 mol.eq boric oxide to be heated in a small can covered by a lid.
2. Mixture pulverized.
3. A gas-generator purged (continuously) with butane and with a bit of HCl in the flask, connected to a jet.
4. Mixture dropped in and generator quickly stoppered.

Another interesting one I hope to do soon is adding Na2O2 to paper tissue and slightly wetting this. I already did this a few times as demo for kids
but never made a video of it. It may take some time before I am capable of making this video, but given the length of time for this project, that
should not be a real issue. Some one else who has Na2O2 also could try this spectacular demo.

Go ahead and make it, multiple shots of the same reaction are good.

In what way multiple shots? do the reaction few times?

No, that reaction is already submitted, but multiple people's videos are good.

ill measure the temperature of the KMnO4 + Break fluid and see how hot it gets

Hkparker, you might want to add also the other video of the KMnO4 and brake fluid reaction, namely this one. It shows the unpredictability of this mixture. It usually carries a delay, but here just after mixing there was a pretty quick
reaction.
There is another older video here that can be used as well. It is a mixture of KBrO3 and sugar, ignited by a drop of conc. H2SO4. Compared to KClO3 in the same instance. KBrO3 and sugar are shock-sensitive detonable mixtures, just like chlorate and sugar, and must never be
ground together. KBrO3 burns with a blue light in that instance and then burns a bit quicker than chlorate. Picture of the comparison can be seen here.
Manganese heptoxide is a highly reactive, explosive oil. I would let anyone who is generating it, be aware of that. I would put the information at
least in the link to the video. I would stress on the fact of preparing it in small amounts, never large amounts. Also letting all know, it's best to
avoid shock, since it's shock sensitive. Certain weak plastics like PETE and styrofoam might react with it. Mn2O7 has seen its way in some chemical
demonstrations before as we know, e.g. the infamous "Fire under water" experiment. But there was hazards mentioned of some related reactions of Mn2O7
(see the attached).
I will say I had a friend who nearly got injured from Mn2O7. I told him all about the compound in high school, I wrote about a page and a half of
warnings. He was a very intelligent person, so I figure I can tell him about it. He did make some. The only thing I forgot to tell him: don't make it
in aluminium foil. He did, and it exploded. But because he listened to some of my instructions he only made a small amount and wore goggles. Nothing
really happened. When I saw the brown marks on his arms next day in school, I asked him about it.
The scientific value of that page (the link in the video page) can be increased by adding in literature, more info about the reactions.
The biggest danger with hypergolics I think is the potential of burning down of one's facilities or living area. This is simple enough to happen, with
one of these mixtures. It is possible, but not necessarily probable, depending on how reckless the person is. The warning at the beginning of the
video is fine, but I think for that reason something a bit more specific like a disclaimer like the one below would also be good in the top of the
linked page:
Warning! To reduce unnecessary fire hazard, the following reactions are best carried out away from any combustibles including nearby flammable
liquids, cardboard, clothing, dry shrubbery, etc. At best on cemented, tiled or similar open areas, with supports. Having a fire extinguisher ready
can be useful. Goggles and gloves are good preventative saftey measures. More energetic reactions may need a face shield, thick clothes and gloves. Do
not grind oxidizers together with the combustibles. Avoid the inhalation of any of the fumes, some of which are more or less toxic.

Thank you for all the links! I will most likely be adding that, or at least most of it, to the description.

I filmed it a few times with the break fluid, smashing up the crystals of KMnO4 causes it to react much faster then the normal size pieces, nd when i
done it, it delayed a bit :S havent seen that happen b4 but it heated up a bit, then stopped for about 10 seconds or so, nd then burst into flames, do
you want me to put them all into one video and then you just cut end edit your self of do u want me to send u the videos and u do what ever?

another cool one is putting aluminum into bromine to make aluminum tribromide its rlly exothermic and bursts into flames, sadly i have no bromine to
do it

You should buy a small amound of sodium bromide, react it with sulfuric acid, collect bromine vapors and chuck in some Al straight away, isnt the best
set up, probly really toxic but it probly works still

yeah, id love to try it out, but 1. i dont have Sodium Bromide (bit expensive aswell) 2. my sulfuric acid isnt a high enough concerntration and 3.
dont have the right equipment to do so
