Inflate Old Tennis Balls！空気が抜けたボールを再生しますセット販売の商品とやり方

[@Alex-vs2fn]

how do they jump afterwards? and what kind of glue is it? the translation from Japanese seems to be wrong for me

[@StuartLeehiqua]

The balls bounce fine. You would never know there is glue inside.

@@StuartLeehiqua Thanks! My 2nd question was, what glue is it (if rubber then why is it white, if not rubber glue, which one)? thanks for all the informative videos you post!

[@StuartLeehiqua]

I do not disclose the contents of the glue except that it is water soluable because this is a formula I made myself and sell it on-line.

I think sealant for bike tubeless tires would work…

[@StuartLeehiqua]

sealant for bike tubeless tires would maybe work if it does not get stuck in the needle but from my experience it often does and gave up trying.
