Ha ha.. if they try the whistles long enough, they’ll also be convinced that they are incredibly good looking, they’re great dancers, and that formerly homely looking guy/gal across the room is starting to look better and better..
Whistle goggles.
Thanks everyone for your ideas
cheers,

Store bought Hydrogen Peroxide is about 3% and totally harmless.
The Torpedoes in German subs of WWII used about a 44% variety which does react with alumnium.
I asked my family Dr about this. He was pretty noncommittal but gave the impression that Peroxide might be worthless as a disinfectant.
A nurse I know tells me that they use rubbing alcohol to wipe down the mouth peices on CPR training dolls.
fyi
I hope this doesn’t seem impertinent, but I wouldn’t consider a family doctor to be someone with particular expertise in this area (I live with a family doctor, btw.).
I’m still interested in knowing more precisely how effective 3% hydrogen peroxide is as a disinfectant. I can’t use alcohol because I’m sensitive to the fumes.
Best wishes,

This is hard to track down, but I’m getting the impression that H2O2 is a pretty good disinfectant. Many references indicate it’s very effective against bacteria, and two references I’ve found indicate it’s effective against viruses as well. One was a set of instructions for using H202 to protect domestic birds against certain viruses that are known to cause problems, and the other reference, in a pharmacology discussion thread was:
The book, Disinfection, Sterilization and Preservation, 3rd edition (I believe that there is a 4th revision now), by Seymour S. Block addresses the use of H2O2 as a disinfectant and a sterilant. This antimicrobial agent has been demonstrated to be quite effective as a hard surface disinfectant in concentrations of 3-6% against vegetative bacteria and viruses.

They treat the incisions during the operations with 3% peroxide and/or iodine.
So it is harmless (in that concentration), and it is disinfectant, there’s no question about it.
