The Science Of It – Bernoulli’s Principal and the Physics of Flight
MARCH IS ENGINEERING MONTH AT THE ORLANDO SCIENCE CENTER AND THIS WEEK, WESH 2 NEWS MARQUISE MEDA IS SHOWING US THE SCIENCE BEHIND LEVITATION. GOOD MORNING GUYS, AND WELCOME BACK TO THE ORLANDO SCIENCE CENTER. MARQUISE MEDA. JOINED BY IVAN ONCE AGAIN. AND USUALLY WHENEVER I MEET UP WITH IVAN, WE’RE EITHER SETTING SOMETHING ON FIRE, BLOWING SOMETHING UP. NONE OF THAT TODAY. BUT WE ARE GOING TO MAKE SOME OBJECTS LEVITATE USING BERNOULLI’S PRINCIPLE, RIGHT? THAT’S EXACTLY CORRECT. YEAH. SO WE HAVE HERE A COUPLE THINGS HERE. I’M GONNA DO A QUICK DEMONSTRATION WITH THIS HAIRDRYER AND THIS PING PONG BALL, SEE. AND I’M GONNA. SHOULD I MAKE IT LEVITATE RIGHT NOW? LET’S MAKE IT HAPPEN. LET’S MAKE THE MAGIC HAPPEN. THEN. THAT’S PRETTY COOL. SO HOW DOES THIS WORK OUT? YEAH. SO THE PRINCIPLE IS BASICALLY THE IDEA THAT FASTER MOVING AIR HAS A LOWER PRESSURE WITH LOWER, SLOWER MOVING AIR AT A HIGHER PRESSURE. AND SO ACTUALLY WHAT’S HAPPENING HERE IS THAT THE HIGHER PRESSURE THAT’S AROUND THE SIDES, SORT OF HOLDING THE BALL IN THIS SORT OF CONE HERE, THIS RECTANGLE WHILE THE LOW PRESSURE, THAT’S THE HIGH SPEED SORT OF KEEPING IT SORT OF BOUNCING UPWARD. NOW, THE REASON WHY IT’S COMING DOWN IS BECAUSE GRAVITY IS PULLING IT DOWN TOWARDS THE GROUND. SO IT’S KIND OF LEVITATING IN THE AIR THERE, KIND OF JUST STAYING STATIONARY IN THE AIR AS YOU GET THE HIGH VELOCITY COMING FROM THE HAIRDRYER, YOU ALSO HAVE THE FORCE OF GRAVITY ALMOST BALANCING IT OUT. SO JUST REMAINS IN PLACE. THAT’S EXACTLY CORRECT. YEAH. COOL. AND I ALSO HAVE HERE JUST A QUICK THING FOR FRIENDS AT HOME. IF THEY WANTED TO SORT OF REPLICATE WHAT THEY SAW HERE, BUT IN A MORE LOW TECH VERSION, I HAVE HERE THESE, THESE LEVITATION THINGS THAT I MADE HERE. THERE’S ALSO A BIT OF A MODEL THIS IS MODEL ONE, AS YOU WOULD SAY HERE. AND IT’S PRETTY SIMPLE. ALL YOU REALLY NEED IS A TEMPLATE LIKE THIS. IT’S A CIRCLE TEMPLATE WITH A LINE GOING THROUGH IT. YOU JUST NEED SOME SCISSORS. A STRAW BENDY STRAW IS BETTER. BUT WE HAVE THESE STRAWS HERE AS WELL AS SOME TAPE TO PUT IT ALL TOGETHER. NOW WITH OUR WITH OUR NEWFOUND SORT OF LEVITATION DEVICES HERE, ALL WE REALLY NEED TO DO IS BLOW ON ONE END, THE BALL ON THE OTHER. AND LET’S SEE BERNOULLI’S PRINCIPLE IN ACTION AT HOME. THAT ACTUALLY WORKED PRETTY WELL. NOW I’M AFRAID TO GO SECOND, BECAUSE I GOTGH ACT TO FOLLOW. ALL RIGHT, LET ME GO FOR IT. I MIGHT NEED SOME MORE TAPE. HOLD ON. SURE. YEAH, I’LL EAR THE EXPERT. I’LL LET YOU HOOK IT UP, FIX SOME THERE. LITTLE AFFIX. ONE MORE RIGHT THERE. YEAH. THERE YOU GO. ALL RIGHT. MOMENT OF TRUTH. WOULD YOU LIKE SOME HELP? YEAH, I’LL TAKE SOME ASSISTANCE. THERE YOU GO. ALL RIGHT, ALL RIGHT. GLAD IT WORKED. FOR A SPLIT SECOND. SO THAT’S BERNOULLI’S PRINCIPLE IN A NUTSHELL. OR BETTER YET, IN A SHELL OF STRAW AND PAPER. BUT I’M GLAD THAT WE CAN MAKE IT WORK. TEACH YOU GUYS A LITTLE SOMETHING THROUGHOUT ENGINEERING MONTH, BUT THERE’S SO MUCH MORE TO LEARN HERE AT THE ORLANDO SCIENCE CENTER AND ALL THROUGHOUT THE MONTH OF MARCH, WE ARE HIGHLIGHTING ENGINEERING MONTH AND I CAN’T WAIT TO SEE ALL YOU GUYS FACES RATHER SOON. WELL, IF YOU WOULD LIKE TO SEE WHAT OTHER COOL STUF

The Science Of It – Bernoulli’s Principal and the Physics of FlightThis week First Warning Meteorologist Marquise Meda paired with Ivan from the Orlando Science Center to discover what makes objects defy gravity and fly… well at least momentarily. As engineering month continues at the Orlando Science Center make sure you’re checking out all of the Centers exhibits and hands on projects designed to show you how the world is shaped by fundamental laws of physics.
