Some people are attempting to counter the spread of coronavirus by making their own hand sanitizer out of rubbing alcohol and aloe. "Per the CDC, hand sanitizer needs to contain at least 60% alcohol," Tito's Handmade Vodka tweeted on Thursday. The company was replying to a user who bragged about using the vodka to make a DIY hand sanitizer. If soap and water aren't available, that's when hand sanitizer could come in handy. Homemade hand sanitizer is also not a great option in general, experts say, despite a shortage in the store-bought stuff.
