Me OMW (on my way) to cut open the cancer treatment machine and put a pellet of cobalt 60 in my mouth:

In an undergrad electronics lab class, the TA suggested I put the function generator leads on my tongue, and play with the parameters. Obviously I know what an applied DC voltage "tastes" like, but he suggested AC, sweeping the frequency. Sure enough, above a certain frequency (want to say 10s to 100s of Hz?), I couldn't feel it at all.
Fun stuff.
I know enough about academia, electrical safety, people and hygiene to find this plausible, reckless, funny and revolting respectively, but not enough about any to know which should win.
Every year you get warned "dont pipette by mouth" because you will sometimes find some 120 year old lab guide that says "pipette by mouth 13ml of 3M NaOh". Those og chemists went hard.
I had both of these in A-level biology somehow. One week we were taught by the ex nurse who was constantly exasperated by us not knowing stuff like how coronary bypass surgeries are performed, and the next a former primary school teacher who would have us doing cutting and sticking exercises on ATP transfer or DNA sequencing. Neither particularly improved our understanding of biology.
