BlastFromThePast Posted April 8, 2013 Posted April 8, 2013 I'm having some trouble finding information on how much BP to use for testing smaller stars. They are 1/4" and weigh approximately .5g. I'm using a paper mortar roughly 1/16" larger on all sides of the star. I just need to know a good starting point, and I am also surrounded by neighbors so I'm not looking to blow up my tube.
BlastFromThePast Posted April 8, 2013 Author Posted April 8, 2013 14 grams? That seems like a lot. But I'll try it
AirCowPeacock Posted April 8, 2013 Posted April 8, 2013 Woah, 14g is way to much for a single 1/4" star!
californiapyro Posted April 8, 2013 Posted April 8, 2013 (edited) yeah, you'd probably fill the tube to the very top with that much! Try 1/4 gram. Edited April 8, 2013 by californiapyro
BlastFromThePast Posted April 8, 2013 Author Posted April 8, 2013 Hahah definitely would've blown that paper tube to bits.
Mumbles Posted April 8, 2013 Posted April 8, 2013 Probably not, but it would have been very wasteful and you would have seen a lot of flame coming out of the top of the tube.
mathiasxx94 Posted April 8, 2013 Posted April 8, 2013 I know that you like cannons dynomike, but we aren't going to shoot stars into orbit I would suggest to but a paper disk over the star to help building some pressure.
AirCowPeacock Posted April 8, 2013 Posted April 8, 2013 Probably not, but it would have been very wasteful and you would have seen a lot of flame coming out of the top of the tube. The lift woulda shot the lift like a starmine.
