Talk:Psi ball/@comment-24580640-20140317220151/@comment-25407503-20140318012442

ever seen those hollow clear bouncy balls that are in claw machines? i usually just think of my psi ball like that. the psi is the airthe shell is flexible but firm. then i slowly harden the shell until my flexible rubber bouncy ball is a rock. dense and strong.

basically. just think of the shell as hardening the outside of the psi ball.

if that doesnt work you could try a shield. and just encase the ball.
