He's without doubt one of the biggest stars of YouTube, and has built a following of galactic proportions! Colin Furze is an engineer, an adventurer and a real life inspector gadget! He's built a secret bunker in his garden and an underground tunnel that links said bunker to his house, plus there's also a subterranean garage that will house his prized Delorean! Oh and he's a bit of a petrolhead as well, although Colin's approach to cars is like his approach to most things in life, ever so slightly unconventional! This is a brilliant episode and one to certainly watch, like and share, while not worrying too much about the lack of a traditional risk assessment!
