YouTube personality Colin Furze has created some explosive, flashy things in the past, such as a Mad Max-style flamethrower guitar, and an explosive Death Star because, why not I suppose.
So it s rare that we see something as simple as a doorbell show up on his successful channel.
Furze introduced the CFDB 500c in a video uploaded on Thursday.
It s a system of three doorbells that account for noise and other activity so that he always knows when the mailman shows up.
But of course, in typical Furze style, we have to have an epic doorbell.
The third piece in the system, made for his bunker, includes an Uzi that shoots bullets into a chute, that in turn drops them into a bowl and hits an alarm.
