0 Comment



>>>IT IS TIME FOR A SCIENCE
LESSON. WE HAVE CHARLIE FROM ASTRO
JOINING US I LOVE THESE SO
MUCH
SO WHAT ARE WE GOING TO BE
FOCUSING ON TODAY?>>>TODAY ONE OF OUR CLASSES OF
ASTRO CAMP IS MAGNIFICENT. WE LIKE TO UNDERSTAND THE
RELATIONSHIP BETWEEN
ELECTRICITAND MAGNUM. IF YOU ELECTRIFY A PIECE OF
WIRE RECOIL YOU CAN CREATE A
MAGNET AND IF YOU TAKE A MAGNET
RUN THROUGH A COIL YOU COULD
CREATE ELECTRICITY.ONCE YOU
GET THAT CONCEPT, WE LIKE TO MOVE ON TO THIS. THIS IS THE FOREFRONT OF
MAGNETS NOWADAYS. THIS RIGHT HERE.>>Brittany: WE HAVE TWO LITTLE
PIECES.>>THE CERAMIC PIECE RIGHT HERE
IS CALLED A SUPERCONDUCTOR. RIGHT NOW THIS IS NOT DOING
MUCH. IF I HOLD IT, IT’S NOT MAKING
ANY CONNECTION AND I CAN PROVE
IT’S A MAGNET BY STICKING IT UP
AGAINST THIS METAL CONTAINER
HERE.>>Brittany: IT’S A MAGNET.>>SO NOW WHAT I’M GOING TO DO
IS TAKE THE SUPERCONDUCTOR AND
PUT IT IN THIS DISH. WE NEED TO BRING DOWN THE
TEMPERATURE. SO COLD THAT IT WILL REDUCE THE
RESISTANCE ON IT AND GIVE IT’S
SPECIAL PROPERTIES.SO AGAIN,
THIS IS THE LIQUIDNITROGEN. MAKE IT 321 DEGREES. FREEZE THAT OUT. YOU CAN ACTUALLY SEE A BOILING
ON THE SURFACE. AGAIN, IT ISNOT MAGNETIC A FEW
MINUTES AGO. WHAT WE WILL DO IS TAKE THIS
MAGNET ON THE END OF OUR
TWEEZERS HERE AND WATCH WHAT
HAPPEN
RIGHT AWAY YOU NOTICE THE
MAGNET IS NOT SITTING FLUSH. I TAKE IT.>>Brittany: IT’S LIKE FLOATING
THERE?>>AS THIS CERAMICACTUALLY
FREEZES, WHAT HAPPENS IS THE
RESISTANCE OF THE MATERIAL
GHOST ALMOST 0 AND IT IS A
MATERIAL CALLED A DIVE MAGNET. IT PUTS OUT A REVERSE OF THE
MAGNET SITTING ON TOP OF IT.>>Brittany: YOU ARE JUST NOT
JUST A SCIENCE.YOU ARE A
MAGICIAN.>>THIS IS USED IN JAPAN FOR
THE MEGATRENDS TO USE A
SUPERCONDUCTOR WITH A CAUSAL
TREND TO RISE IN TROUBLE AT
OVER 300 MILES AN HOUR.>>Brittany: SO THEY USE THIS? IN REAL LIFE. IT’S NOT JUST SO THAT WE CAN
SEE IT? OF MAGNETS.>>Brittany: THAT’S AMAZING. IT’S SOMETHING YOU ALL DO AT
ASTRO CAMPS THAT KIDS CAN LEARN
ABOUT AND IT’S FUN THEY REALLY
ARE LEARNING.>>ABSOLUTELY. THIS IS WHAT WE DO WITH KID
STAND AROUND THIS SHOW THEM
WHAT A SUPERCONDUCTOR CAN
ACTUALLY DO.>>Brittany: IF SOMEBODY WAS TO
FIND OUT ABOUT ASTRAKHAN, HOW
CAN THEY DO THAT?>>GO TO OUR WEBSITE AT
