This was my moms hacky sack from high school. She never used it much, so it was really stiff when she gave it to me. Last year I gave it the life it deserved by bringing it everywhere, and playing with it over the summer really broke it in and softened it up. In the recent sack craze, I brought it back to school, and it ended up tearing. I used this opportunity to remove the plastic beads (on the the left in the photo) and make my own creation
Using the density of the two materials I wanted to use, my target weight, and my target fill percentage, I made this:
Bag: 7g, 2.25” diameter
Plastic pellets: 8g
Copper bbs: 45g
Total weight: 60g
Filled ~55%
I closed the hole at the top with a sewing machine, and this thing plays just as well as any suede multi-panel foot bag I’ve used. Only mild issue is that the copper is 13 times denser than the plastic, making it sink to the bottom easily and deadening the pop.
Just wanted to share this to encourage people to get creative with what they have on hand.
If you have any advice for Frankensteining old foot bags, please share. Peace
