    How do vacuum cleaners work?

    How do vacuum cleaners work?

    Vacuums are like magic. You press a button and POOF – they can suck up all kinds of stuff: crumbs, cat fur, even coconut shrimp. But how do these handy dandy machines work? We asked mechanical engineer Tiffani Teachey to help us find the answer.

    Would a flashlight turn on at lightspeed?

    Would a flashlight turn on at lightspeed?

    What do a cheetah, a rocket ship, and champion sprinter Usain Bolt have in common?  If you guessed they’re all way slower than your average beam of light, you’re correct!  Nothing in our universe moves faster than light. But recently, we got an interesting puzzle from a listener: if you were able to travel at lightspeed, and you turned on a flashlight, would it turn on?  We asked astrophysicist Amanda Farah to help us investigate.

    Why do we jump when we get scared?

    Why do we jump when we get scared?

    If you’ve ever jumped right out of your seat when watching a scary movie, you know that sometimes your body has a reaction to being surprised or frightened. One of our listeners wanted to know why that happens, and we asked neurologist Sarah Benish to help us understand.

    How do microphones work?

    Imagine this: you’re at a karaoke competition. You grab the microphone, belt out your favorite song, and the crowd goes wild! Everyone can hear your voice, thanks to your handy dandy microphone. But how exactly do these snazzy little machines work? We asked mechanical engineer and science educator Tiffani Teachey to help us find the answer.

    Why do our lips get chapped?

    Why do our lips get chapped?

    We’ve all suffered with chapped lips in the winter: itchy, flaking, sometimes even bleeding. Yikes! One of our listeners wanted to know how this happens, so we asked dermatologist Roxana Daneshjou to explain.

    Do eyeballs grow?

    Do eyeballs grow?

    Eyeballs! They’re squishy orbs in our skulls, made of lots of different parts that work together to send visual information to our brain. But do they get bigger as we grow from babies to adults? We asked eye doctor Stacey Pineles to help us find the answer.

    Are you a pupil with a burning question? Send it to us at BrainsOn.org/contact, and we’ll help en-vision the answer!
