Also inflated it with air using a basketball pump.

Got so tight the shin went shiny. :-D)))

I could flick it with my finger abd it went 'thrumm' 'thrummm', like a drum. :-)

I tried with mine.

Was hoping it would go BANG, with a ball going over my shoulder on its cord, and the other hanging out the window. LOL.

But it didn't.

Not finished with it yet. Muahhh harrr harrr >:-]

With air, really? I´d loooove to see that on video!
