ISO a Paintball-like kit

[bienejen]

I did a search but nothing came up. My kids recently played Gellyball and I need something to document it. For those curious: "GellyBall Blasters shoot a soft gel ball, much like an Orbeez that your kids probably already play with! Shot from easy-to-use Blasters, the soft GellyBalls bounce off kids or simply disintegrate, leaving no stain, mess or sting."
It's basically like paintball for all ages with no mess or pain.
