Okay... So we ran into a bit of a problem...We made some 12 panel juggling balls out of ultra-leather based on this pattern that has given a very nice round shape. The weight of the panels is 13 grams. The problem is that the plastic millet we used was hilariously too heavy...Like, the ball is currently at around 240 grams. We're trying to end up with a ball in the 120-130 gram range.If my math is wrong please let me know, clearly it was way off the first time...For a 1.5" radius ball (3.81 cm), the volume is therefore 231 cubic cm. Which means...our millet density should be roughly .5 grams per cubic cm. Is that correct?If that problem is accurately fleshed out, we are now having a very hard time sourcing plastic millet at that density. Do you guys have any suggestions about where to find an applicable fill of that weight?One of the other problems is that we are currently in China, and having an even harder time given the language barrier and foreign markets and such.On that note, can someone more wizardy than me help to figure out the density of these plastic jewelry beads? The website says there are roughly 4,500 units per 500 grams, the beads are 6mm per bead. Not sure if these would work, that seems awfully heavy again.We've looked at some 3d printing millet suppliers but everything we have found is close to 1 gram per 1 cubic cm of millet. If anyone has any stateside suggestions also, I am heading back to New York for a couple days next week and could pick something up if I were able to source it in time from a supplier, amazon, anywhere, et cetera.Thanks DIY --- YOU'RE OUR ONLY HOPE!!! via /r/DIY http://ift.tt/2gREk7K
