Warning, this is the most hair-raising and exciting episode of Blue Peter ever! Radzi conducts four million volts of electricity to shoot lightning bolts from his hands. Plus four motorbike riders race around the infamous Globe of Death, and we're joined by Henry Danger himself.

This episode of Blue Peter has got it all. It's jam-packed. In fact there is so much in it, we'll struggle to tell you about it all right here. Especially when we spend so much time talking about how much is on the show. Oh, we've run out of space now. Watch it!
