Reasons for my voting on two options which were not commonly voted on:
ISTP: Robotics, explosives, utilizing chemistry for dangerous purposes, microwaves, etc. These are the geeks that are most likely to end lacking body parts due to their geekery.
I will verify all of those. Except that my worst injury to date is a large scar across the top of my left hand, and weapons should be added to the list as well.
I've combined all of those before..."modified" an R/C plane, to hold and fire remotely "missiles". The missiles were model rockets with the area where the parachute would normally go filled to the max with gunpowder and other materials taken from disassembled fireworks.
As for the chemistry aspect, making thermite is a lot of fun.
