We've hit episode eight of Totally Bonkers Guinness World Records, the programme that brings together the weird and wonderful world of record-breaking.

Viewers in the Uk can tunes at 8pm on ITV2 tonight to see some of the most entertaining Guinness World Records and the brilliant characters who set them.

Show eight sees such incredible feats as Spanish whizz kid David Kalvo record the fastest ever time to complete two Rubik cubes simultaneously underwater, and the fearless Sandra Kier from Germany quite literally smashing the record for the fastest time to run through ten locked doors.

As always, we'll be live tweeting during the show at http://twitter.com/gwrnews, giving you links and extra information about some of the records and holders featured.

You can join in with the conversation by using the hashtag #bonkersgwr.
