Just an FYI, gel/orbie blasters are being discontinued due to lawsuits. They are being clearanced out at most brick and mortar stores, 60%+ off. Walmart has the beads at $2.50 for 20k.
Obviously don't have these around small children. Tell your kids not to eat them. They are the same things that are in diapers, they swell when exposed to water. When you shoot them at something hard they shatter, and will help with water retention in soil.
Lawsuit is over a 10 month old apparently ingesting them. Sad for the kid, but that's on the parents. They are clearly labeled for teenagers and older.
