Technician, heck, there's a management opening at Bompas & Parr:

Work with Bompas & Parr
April 2012
Sam Bompas & Harry Parr are delighted that the opportunity has arisen to create a new post of General Manager. Bompas & Parr has grown steadily over the last 5 years and now the appointment of a General Manger, will allow a broader spectrum of creative work to flourish.

About their "Explosion Service" that I mentioned earlier:

Wedding cakes can be brutally stodgy. Blowing the cake up spares the stomach after a heavy meal and is a good way to wake guests up for the speeches.

For a fee a trained explosives technicians will lay charges within your wedding cake (or food of choice) which you can detonate at the climax of the evening. To launch the service Bompas & Parr collaborated with renowned photographer Ryan Hopkinson on photographs exploring what happens when powerful explosives are detonated inside jellies.

On making a booking an explosives technician (member of the Association of Stage Pyrotechnicians) will liaise with your wedding cake provider on setting the charges and arrange risk assessments and method statements with the venue. They will attend on the day of the wedding to set the explosives, rig the detonator and supervise the explosion. All explosives are transported within containers meeting the MoDs SEAP 4 security standards as referred to in JSP440.
