Hey there Smarty Pants. Trusty narrator here welcoming you back to another curiosity filled episode of Smarty Q where I tackle some mind blowing questions sent in by you the Smarty Pants listeners. I've got some great stuff today, so let's dive right in. First, Kyle, aged six and a half from Orlando, Florida, asks, why does your head go forward and your eyes close when you sneeze? Cool question, Kyle. Sneezing is your body's way of clearing your nose when dust, pepper or pollen tickle your nasal passages. When you sneeze, air blasts out at over 100 miles per hour. To protect your eyes from germs and pressure, your brain automatically makes the muscles around your eyes blink. It's a built in reflex. Your head jerks forward because dozens of muscles contract at once to push out the sneeze. It's teamwork between your diaphragm, your chest and your head muscles. No thinking required. Calvin, Finnegan and Josephine ask how is it? If you cover yourself with a blanket and stand in front of a mirror, does the mirror still show your reflection? Ooh, great question. A mirror doesn't show what's under your blanket. It shows the light that bounces off whatever's in front of it. Right now, when you hide under a blanket, you may be invisible to people, but the mirror still reflects the blanket because light from it hits the mirror and bounces back. So mirrors don't have X ray vision, they simply reflect the light they receive. Lily, age 8, asks, can ants see germs? Nope. Even though ants are small, they can't see germs, but they can sense things that help them stay clean. Germs are microscopic, meaning humans need microscopes to see them. Ants, of course, don't use microscopes. Not only that, but ants eyes are better at detecting shapes and movement, not tiny details. However, ants do have super strong smell sensors in their antennae, which can detect chemicals that signal danger or contamination. Okay, three questions down and a few more to go and we'll get to them right after this quick break and a word from our sponsors. Now back to smarteqs. Jamie from Spotify asks, why are stopwatches so precise? Stopwatches are precise because they rely on high frequency oscillators that measure time in tiny beats. Mechanical stopwatches use springs and balance wheels that tick many times per second, while digital stopwatches use quartz crystals that vibrate 32,768 times per second. Those vibrations allow them to measure fractions of a second very accurately. And finally, an unknown smartypants on Spotify asks, why are people afraid of robots, puppets, and animatronics? Ah, spooky. Cool question. The answer lies in something scientists call the uncanny Valley. When something looks almost human, like a realistic robot or puppet, your brain notices the small differences and feels uneasy. Humans have evolved to recognize human faces instantly, so when a robot smiles, they but its eyes don't move naturally. Your brain detects something is off. That mismatch between familiar and strange triggers discomfort or fear. Personally, I'm more scared of the pizza at Chuck E. Cheese than the animatronics. And that wraps up another curiosity packed episode of Smarty Q. Big thanks to our Smarty pants for their amazing questions.

Until next time, keep on smarting, Smarty Pants.
