  • You know that the best way to prevent the spread of coronavirus is to wash your hands.

  • Wash your hands, doo doo, doo doo, doo doo.

  • Wash your hands!

  • Butwhy?

  • It’s because soapregular soap, fancy honeysuckle soap, artisan peppermint soap, just any soapabsolutely annihilates viruses like the coronavirus.

  • Here’s how:

  • This is what a virus, like coronavirus, looks like.

  • It’s a bit of material surrounded by a coating of proteins and fat.

  • Viruses easily stick to places like your hands, but when you rinse your hands with just water, it rushes right over the virus.

  • That’s because that layer of fat makes the virus behave kind of like a drop of oil.

  • You can see it happening in this demonstration.

  • Oils are just liquid fats.

  • What happens when you pour oil into water?

  • It floatsit doesn’t mix.

  • But add soap

  • And suddenly that fatty oil dissolves into the water.

  • That’s because inside, soap has two-sided molecules.

  • One end of the molecule is attracted to water, the other end to fat.

  • So when the soap molecules come in contact with water and fat, these dual attractions literally pull the fat apart, surrounding the oil particles and dispersing them through the water.

  • Let’s go back to our coronavirus molecule with that layer of fat holding everything together.

  • When it interacts with soapbam!

  • The fat gets pulled out by the soap.

  • Soap literally pulls apart and demolishes these viruses.

  • And then the water rinses the harmless, leftover shards of virus down the drain.

  • But, and you know where I'm going with this, it takes time for this effect to happen.

  • 20 seconds, to be specific.

  • To show why, we ordered this lotion that mimics viruses and their fatty layers.

  • It glows under a UV light.

  • If you just rinse your hands under regular waternothing comes off.

  • If you wash for just five seconds or 10 seconds, your hands are still covered.

  • The virus is still here, able to get you and others sick.

  • But 20 full seconds:

  • Now the soap is actually destroying the virus.

  • Hand sanitizer works too, because it’s mostly alcohol, and alcohol works in a somewhat similar way to soap, breaking down that fatty layer.

  • You need a high concentration of alcohol to make that work.

  • The CDC recommends hand sanitizers with at least 60 percent alcohol.

  • But even with 60 percent alcohol, the CDC recommends using soap if you can.

  • If your hands are sweaty or dirty when you use the sanitizer, that can dilute it and diminish its effectiveness.

  • As for soap, just any old soap works.

  • You don’t need soap marketed as antibacterial, even.

  • The FDA says skip itthere’s no proof it is any more effective.

  • Just be sure to wash your hands for 20 seconds.

  • That’s "Happy Birthday" twice.

  • Or the chorus to Lizzo’s "Truth Hurts.”

  • Or Prince.

  • Or Eminem.

  • Or even Dolly.

  • Just as long as it’s 20 seconds.

  • And youre using the ultimate virus annihilator: soap.
