if you guys ever go woburn safari park go in the kids arc play room,, there a 30 foot vertical slide there where kids play on it,,,, i went on it ( after chucking my 3 year old daughter down it first,,,,, no honestly i did

) and fuck me its scary,,,,, got her out the arc play room though,,, infact she wont go on slides anymore since then,,,,,,
but seriously theres a similer version there if ya wanna have a test to see if you trust it
