I'm going on holiday soon, and wondered if I can take my IPad mini (which has a cracked screen) on a plane?

Hi,

Nearly all devices are allowed on planes, cracked screen or no cracked screen. You MUST however make sure the iPad is on Airplane Mode, as it could interfere with the plane otherwise.

Yes.
Of course you can take your cracked screen iPad mini on a plane.
There are no explosives in an iPad mini or any iPad, iPod or iPhone.
