That’s OK. I have the proper safety equipment: a lab coat, goggles, and a top hat.
Remember, no matter how late at night it is, if you’ve soaked the cotton stoppers to the fruit fly bottles (in order to kill them so that you can count up mutations under a lens - hard to do if they are not inert) and you decide that you are too tired to continue, do not put them into a refrigerator to “keep them fresh overnight.” Very definitely don’t put them into a refrigerator that is not rated for flammables.
No, I’ve never done it, but I’ve seen the photos taken after the explosion.
