So here's the idea: in light of all the Corona stuff happening, how would you feel about making next week's chemistry club about making and testing different DIY hand sanitizers?
I'm thinking we could make something along the WHO guidelines, do a science-y bootleg one, do a bootleg bootleg one, and try to engineer a custom one. We could test them with bacteria in petri dishes (though the reaction upon contact with skin is another important thing we'd have to consider - that would be harder to safely test).
I know there's been a lot going around about why you shouldn't make your own hand sanitizer (mostly it seems the concern is missing the ideal >60% concentration of alcohol mark), but it'd be fun to do the test regardless to see if there's any weight to that.
We'd need 99% isopropyl, 91% isopropyl, 70% isopropyl (I could come in early and make all of these just with dilution from a stock solution), aloe vera gel, 98% glycerol, 3% Hydrogen Peroxide, DI, cotton swabs, and Petri dishes
