YT2095

is due to be tested on the 10`th September this year: http://press.web.cer...8/PR06.08E.html
so we`re not far off from creating tiny Blackholes now!
anyone for a round of Golf?

since Last years event went so well, it was agreed that this should be a yearly occurrence, we had a small group of about 50 people attend and enough food for each as well, and the word has gotten around about how excellent the display was that I expect there will be double that amount this year
Like last year, we`ll go for a starting time of 7:30pm, although those bringing fireworks that require setting up need to arrive earlier.
the grounds are privately owned and only accessible via a large lockable gate.

also if you look to the bottom (hit the down arrow twice) you`ll see a School, and a long road besides it leading to allotments, that`s where the Gate is. and on the other side you can see our Community building.

the Schools address is:

St. Paul's C of E © Primary School
Robert Road
Tipton, West Midlands
DY4 9BH.

and for those that come by Train it`ll be Tipton Train station.

feel free to come along (there is no entrance fee) and bring your own fireworks with you as well, last year we fired in 2 sessions so there`s plenty of room and time for everyone that brings their own. I`ll be having a word with the local Photographic Society to attend also.

here`s last years thread: http://www.pyrosocie.......tipton&st=0

I came across this on another site and thought of Bonny:

"The nine chemicals to be controlled under the new regulations currently have a wide range of legitimate uses, such as ammonium nitrate, which is commonly used in agriculture as fertilizer. The chemicals are: ammonium nitrate; nitric acid; nitromethane; hydrogen peroxide; potassium nitrate; sodium nitrate; potassium chlorate; sodium chlorate; and potassium perchlorate."

I`m not Quite sure how to Start this thread off, but I`v discovered something part by accident and part by design that I`m MORE THAN sure will interest you all (I think).

it` started with something I`v known as a kid but had no explanation for, that if you add sodium hydroxide to sugar soln it will turn very syrupy like honey and no longer be sweet, so I tried this with calcium metal in saturated sugar soln soln a month or so ago to get rather astonishing results, Yes the calcium reacted giving off hydrogen, but instead of it going cloudy to make lime water the soln stayed Clear!
cut a long story short I evaporated this clear liquid off to leave clear sugar like crystals, but it`s NOT sweet!
and when you add it to enough water it will turn cloudy.

basicaly I made Calcium Sucrate (or so my research over the last few weeks have said).

now Apparently this will work with all Group 2 metals (and I know it works with group 1), so I thought Perhaps this has an interesting potential in Pyro as a color donor.
most others seem to have the color doner in the Oxidiser, with Very little in the actual Reductor! (benzoates excluded).

so I tested Calcium Sucrate with Amperc, and not only did it give off a good and Very visible Red color (as good as any Strontium) it also crackled quite a bit like dragon eggs (but not as violent).

now this was only a .25 gram mixture on a steel plate, I have no idea if the crackle would happen if used in a device or star or something, nor will I test this (no License), BUT if anyone Else out there suitably equiped to make some and test it, I would Really like to see my results reproduced and verified independantly.

the Potential here is REALLY! exciting!
since it will happily accept accept a metal in the +2 oxidation state, and we all know Copper does the +2 quite happily also, and the Other color contributers Ba, Sr are group 2 andway, and I know Sodium works too because that`s what lead me down this path in the 1st place

currently I have some Barium Hydroxide that I made this morning drying out, and hope to make a few tests as to how viable it is to make Barium Sucrate.
but again, if anyone else is equiped to make this before me Go for it!

I for one am quite astonished at the Color and crackle effect I`v just seen, I Had to share this data with you!

just an idea I`ve been toying with in a few thought experiments.
as we all know traditional fireworks employ Additive Color synthesis, we have the black night time shy and then we add Color in the form of Light. how about the Other way around, we already Have the light during the day, and we can choose what colors to take away or reflect!

it would`nt be any more expensive to do either, as it doesn`t necessarily have to be all colored smoke devices being deployed, how about tiny bits of colored Foil or flame proofed Day Glow fluorescent paper/card.
all cut up into small pieces and either rocket or mortar deployed as a cylinder with a time fuse and a small BP charge to blow the colored paper/foil effects out of the tube when it gets to the correct height.
and Unlike traditional fireworks these won`t go out (burn out) and should be quite a bit lighter in weight too.
even plain old tinfoil should give a great Glitter effect and last for ages before touchdown, colored foils should give a nice effect too.
I thought about using one of the paper hole-punches, the sort that keeps the little cut out dots in the base and using that, but how about a Paper shredder! feed it through once and then take it out and feed it through sideways to get smalled squares.
it may even be possible to do Streamers like Party Poppers?

I`m still thinking about an idea using Water and flash charge or maybe sugar crystals and a simple BP charge to see if an artificial Rainbow could be made...

so, if anyone here has rocket engines to test, rather than put a dummy payload on it, try one of these ideas for me please, it`s just as inert as a bag of sand or water or whatever you use, and it will give some interesting data to boot
