I present to you the following paper:
Focht DR III, et al. The efficacy of duct tape vs cryotherapy in the treatment of verruca vulgaris (the common wart). Arch Pediatr Adolesc Med October 2002;156:971-4.
I'm a little torn as to what to think of this research -- on the one hand it presents an effective and cheap treatment for a common problem, as well as another use for the mighty gaffa tape -- on the other hand though, it could deprive honest men and women of science of an excuse to get out the liquid nitrogen. This is troubling because liquid nitrogen has an extremely high awesome-per-millilitre (A/ml), depriving doctors of such important resources now could leave the developed world with a serious dearth of mad scientists ten years down the line. In times of recession we should be striving to support our nation's mad scientists, for without them the Van de Graaff generator and lightning rod industry could collapse.
It could be as bad as when they stopped alchemists from boiling mercury in small rooms.
