Bill Nye the Science Guy has returned to his roots of explaining scientific concepts, but on a different platform – TikTok.On Thursday, the former TV show host posted two videos on the platform, which is mostly used by younger people, to demonstrate why the public should wear masks to prevent the spread of the novel coronavirus.In his first video, Nye starts by explaining why people in the scientific community want you to wear face coverings when you’re out in public.“Face masks, like this one, prevent particles from my respiratory system from getting into the air and then into your respiratory system,” said Nye. “Blocking the movement of air is an old trick.”Nye then demonstrates how scarfs can block the movement of air to keep our necks warm, but they don’t block air enough to stop his breath from blowing out a candle.Afterwards, Nye brings out a homemade face mask with two layers of cloth and a pipe cleaner. Although the mask is simple, Nye says it “blocks the movement of air very effectively.” He tries to blow the candle out with the mask over his face, but he can’t.“If you’re wearing one of these, you’re protecting yourself and those around you,” said Nye. @billnye ##WearAMask ##LearnOnTikTok ##TikTokPartner? original sound - billnye In his second video, Nye brings out an N95 mask, which are used to block particles in the medical community and by those cutting their lawns. He tries to blow the candle out again and it’s even more effective than the cloth face mask.“So, the reason we want you to wear a mask is to protect you, sure, but the main reason we want you to wear a mask is to protect me, from you, and the particles from your respiratory system from getting into my respiratory system,” said Nye. “Everybody, this is a matter, literally, of life and death. And when I use the word literally, I mean literally.”“So, when you’re out in public, please where a mask,” Nye ends. @billnye ##WearAMask ##LearnOnTikTok ##TikTokPartner? original sound - billnye Nye isn’t the only one advocating for face coverings. The Centers for Disease Control and Prevention (CDC) and other public health officials are also asking Americans to wear masks in public to help slow the spread of COVID-19, which has killed more than 133,000 people in the U.S. and the cases are continuing to grow.A growing list of states are actually requiring residents to wear face coverings before leaving their homes. 2434

BUFFALO, N.Y. — Several Buffalo police officers have come under fire for putting tape over their name tags while patrolling a protest in the city on Tuesday.Black Lives Matter protests took place in the city on Tuesday and Wednesday. Photographs from Tuesday's demonstrations show officers covering their name tags with pieces of black tape.The Buffalo Police Department Manual requires officers to wear name tags on their "outer most garmet."Buffalo Mayor Byron Brown said Wednesday that officers hiding their identities is unacceptable."Police also need to act responsibly by displaying their names and badge numbers as they're required to do," Brown said.However, both Brown and officials from the Buffalo Police Department added officers might have felt the need to hide their identity because several officers have been doxxed or had private personal information about them shared publicly on the internet. Doxxing has led to threats toward the officers and their families, officials said."Attacking officers through social media to get your points across, attacking their families, you've way crossed the boundaries," Buffalo Police Deputy Commissioner Joe Gramaglia said.The department says that it has addressed some threats toward officers and their families. Gramaglia later added that police need to abide by the manual rules and wear their nametags despite the threats.An official with the Buffalo Police Union said that the officers' decision to cover their name tags was reasonable."I don't blame them at all," the representative said. "We recently (last week) had death threats made to an officer, and the threatening individuals had information on the officers home address, wife and child. He had to move them for their protection.""We understand that we as police officers are targets, our families didn't sign up to have harm brought to them because they have a husband/father that is a police officer."Organizers of Tuesday's protest say covering nametags violates transparency laws."This just shows the type of corruption we have right here in WNY," said Darien Chandler, the founder of WNY Liberation Collective.All officers appeared to have their names displayed during Wednesday's protests.Gramaglia says the department is looking at which officers hid their name tags. Discipline could be handed down.This story was originally published by Hannah Buehler on WKBW in Buffalo. 2407
