In my undergrad university we had a predental class that was awesome in letting us show how good our manual dexterity was. We carved 5 projects out of wax, a canine, a central incisor, a bicuspid, a molar and one more of our choosing that was actually a wax up on a crown prep. Now I have 5 teeth that I have carved myself and plan on showing to adcomms if they ask me about manual dex. You could do the same yourself, just try to find a book that has instructions on how to carve teeth from wax. I don't know where this instructor got the information for the class but it looked like it came out of an old textbook from dental school or something....Other things that might impress are repair skills (cars, computers, other electronics), art, sculpture, haircutting?, whatever you do, don't mention video games, even if you could kick everyone's butt at Halo! 🙂
