  • K'NEX 

  • Not the best but I give you credit for making some flash powder

  • ??????????????

  • Good job.

    Even though the flash powder doesn't give a thud when deflagrating, I like that it was still pretty fast and gave off glittering sparks.

  • woowww there was lightning in the clouddd thats cool

  • Hmm... I use Potassium Permanganate and Aluminum Powder in a 8:2 ratio... Permanganate is actually cheaper that Nitrate when you buy it at the store, because 5 pounds of permanganate is $30.00, and 5 pounds of nitrate is $40.00.

    I get my aluminum powder of the internet.

  • instead of a penny lets put knex to supersmall things

  • hmm that seems very slow... not even as fast as good black powder.

  • I know, i used a weird ratio for this.And, i didn't have scales at the time so i was measuring 50/50 and then adding some sulfur. I have now got better scales and i am using 5g KNO3 4g MgAl and 1g S. My scales measure to 0.01 grams. I might post another video of my newer video.

  • hey (: try kclo3 and magnesium 1:1 OR ammonium nitrate and magnesium 3:5 by volume (:

  • I had my ratios all wrong in this video, sorry. I'm not allowed to get kclo4, let alone kclo3 with is more sensitive.

  • not allowed to get kclo3? have a video on how to make it from matches qx hehe and you should use paper fuse hehe.. kno3 in hot water, paper in, let it suck it all up, dry use.. :D fx. roll it up for better burn rate

  • Nice flash :D

    where did you get MgAl of that mesh # and how much was used? 5*

  • Thank you. It's from Ebay and it is 400-700 mesh, i brought it off someone called tinytimjukeboxes, he offers 250-500 mesh but just message him and ask him for the highest mesh and the highest quantity. He should do you a first time deal. I would say, by looking at the video this is around 2 grams? I didn't weigh stuff then. Message me if you need the link for the auction.

  • i bet that kid makes his own. not that hard. i heard u can make it from like a blender or food grinder. with some lead balls it should grind. but idk mabey ill try it 2moro

  • Hi, no. I buy all my chemicals of Ebay, magnalium of ebay, quite a good deal. Didn't you read the previous comment? Magnalium is mg an al, not al

  • o lol i was actually talking 2 u. like the kid that sold it 2 u. was it like from a company? or from a person?

  • You've confused me but i'll try to answer...I brought it of a website called Ebay, from a seller called Tinytimjukeboxes.
