I went on a search earlier for foam(...polystyrene?) balls (like the ones for making X-mas ornaments and Solar System mobiles), and they can be had for cheap in 1.5", 2", 3", etc, but not 1.75". Which possibly accounts for blaster-makers choosing that size, and definitely contributes to the $25 price tag on 5-ball refill packs on ebay. =(

I'm not going to step over these and keep walking NEXT TIME I see a bunch of them rolling around on the floor at Savers or Goodwill, I'll tell you that much.
