oh nice nice...yeah you should totally embrace the human pincushion act. especially deep tissue pin cushion...a couple of guys i know Zomora the torture king and Maruggun the Mystic both do the deep stuff....like through the bicep or under the tongue and out the neck/chin area....totally crazy. ummm well there are lots of things to look into. even with blockhead you can get to a point doing bigger nails, screw drivers, and even power drills...(just make sure the bit has been umm...made safe) and if you can do that i bet learning mental floss would be cake. I think I am going to learn that one myself to add to my stunts.
I do basic stuff mostly, fire eating and manipulation, sword swallowing, human blockhead, pain proof hands (traps and what have you), I also eat glass, and been throwing knives although i haven't taken that to the stage yet. i am currently in the works of a ladder of machettes, a bed of nails, and an electric chair for a electra act. also looking into building a spidora box. (all the builsing stuff is going to be done through my friend Bash) so hopefully we build these up nice. I saw you are in Vegas...do you happen to know Brianna Belladonna? or Grace LaFluer? both are sideshow performers from Vegas also.
what else do you know how to do aside from blockhead?
