I am applying for an engineering apprenticeship with an Airline in the UK but they ask for me to bring evidence of my own work (DIY ect) to show that I have some sort of interest in construction and engineering.
My huge issue:
The only things I have ever built (many thanks to Facepunch) have been ghetto weaponry.
In the past I have built a working portable flamethrower (I just wanted to see if I could do it, had to take it apart as I needed the pressure washer to clean the patio), a really god awful looking crossbow, a potato bazooka, a battery gun, smoke grenades and numerous different knives.
The only non lethal thing I ever made was Fiddle Hero, where I shortened a guitar hero controller by about 8 inches then made it possible to strum using a bow:

Old photo, ignore the long beard and nose piercing, they're gone now.
I don't want to walk in and be like "Hey I have never built anything ever, no sir" but I also don't want to wonder in and present a long list of most likely illegal contraptions and come across as some creative but dangerous psychopath, especially as I'll be working in a fuckin' airport.
