Projects that have been sponsored include a spring-loaded hidden blade and grappling hook from Assassin's Creed, an artificial-turf-covered BMW E30 containing a hot tub and barbecue grill, and a bunker underneath his back garden to promote Sky1's television series You, Me and the Apocalypse.

[6][7] On 5 May 2014, Furze posted a video to kick off his 3-week long X-Men characters special by designing a set of realistic Wolverine claws based on a pneumatic system.

[8] On 23 October 2015, Furze released a video showing off the start of a new multi-part build, in which he would construct a Hidden Blade to promote the new Ubisoft game, Assassin's Creed: Syndicate.

In November 2015, Furze constructed an underground bomb shelter beneath his garden, as part of a request by Sky1 to promote the series You, Me and the Apocalypse.

[9] The bunker contains a corridor and a large main room, as well as a fully functional air filtration system and has an entrance shaft concealed by a garden shed.

It worked by having a pivot 3 metres in the air with a 7.5-metre extendable arm and seat on one side, and a 1 tonne concrete block as a counterweight on the other.

[17] On 14 October 2010, it was announced that Furze had modified a mobility scooter to give it the ability to reach 71 mph (114 km/h) in an attempt to enter the Guinness Book of Records.

[20] On 30 March 2017, Furze posted a video showing a restored 1960s dodgem fitted with a 600 cc (37 cu in) motor cycle engine producing around 100 bhp (75 kW).

Furze made his television debut by appearing as the 'Mystery Guest' in Episode 1, Series 3 of Russell Howard's Good News, where he showed off his mobility scooter project.

He appeared as a guest and "challenge" in the third season of the German TV game show Joko gegen Klaas – Das Duell um die Welt.

[25] Colin Furze authored This Book Isn't Safe, a collection of projects intended for children and adults to recreate at home and spur an interest in engineering.
